of 1763. He considered it coincident with the public law, particularly in view of the American discovery, in 1792, of the mouth of the Columbia, to order an exploration of the Missouri and its branches to their sources, so as to trace out to its termination on the Pacific soine stream "which might offer the most direct and practicable water communication across the continent for the purpose of commerce."

This measure was originated before the ratification, on 31st October, 1803, of the treaty whereby the French republic ceded to us the ancient province of Louisiana.

The Florida cession of 1819 from Spain followed, and then the admission of Texas in 1846, retaining her public lands. The treaty of that year with England, and the Mexican cessions of 1848 and 1853, completed our southwestern limits on the Gulf, the Rio Grande, thence westward to the Pacific, and giving us frontier on that ocean and Puget sound of one thousand six hundred and twenty miles; said cession of 1848 adding to the sea line we had on the Gulf of Mexico, under the Spanish cession of 1819, four hundred miles of coast, extending from the mouth of the Sabine to the Rio Grande, thus making our seacoast line on the Atlantic, Gulf of Mexico, and on the Pacific, equal to five thousand one hundred and twenty miles.

By these important acts the public lands have been increased in extent nearly seven times their area at the close of the last century, and are now seventeen times the surface of the kingdom of Prussia, including her territorial increase growing out of the recent war with Austria.

They are in still larger ratio greater in area than England, Wales, Scotland, Ireland, including the channel islands and the other British European possessions.

The area of our domain was estimated some years ago at upwards of 1,450,000,000 of acres, but is now found, by calculations based on more specific data, to equal 1,465,468,800 acres.

The soil of the flourishing States of Ohio, Indiana, and Illinois, once a part of the national territory, has nearly all passed into individual ownership. The undisposed of portions of the public domain, in greater or lesser extent, exist in the northern regions of the Lakes Huron, Michigan, and Superior; in the southern, east of the Mississippi and fronting on the Gulf of Mexico; in the tier of States having that river as an eastern boundary, and still further westward in all the other political communities, States, and Territories, stretching to and over the Rocky mountains, the Cascades, and Sierra Nevada, extending to the Pacific slope, with that ocean as a frontier, and the rich mineral State lying immediately cast of and adjacent to the two great States of the Pacific.

What is the system, founded in legislation, by which this half continent is so dealt with and required to be administered that our own people and immigrants who propose to enter the American family can secure rights to settlements with complete, absolute, and indefeasible grants?

It is by the establishment in the first instance of surveying departments, now ten in number, with sixty-one land districts, each, when in operation, having a register and receiver to file applications, and take the steps required by statu tory provisions as preliminary to the acquisition of inceptive and complete title. In our present system of surveying the public lands, the lines under the first ordinance started from eastern Ohio; afterwards advanced into the old Natchez settlement, in the present State of Mississippi, and now penetrate to the southernmost cape of Florida, sweeping around the Pacific coast, from San Diego to the Straits of Fuca. Ever growing and extending, they now cover an immense surface. This was not the work of a single period, but of years of congressional legislation, and anxious and patient thought on the part of those from time to time intrusted with the execution of the laws.

It is a subject of interest to trace the progress of the improvement of the sys

tem since the treaty of Grenville, of 1795, the first public act by which the Indian title to lands northwest of the Ohio river was extinguished.

For the better regulating the surveys, as well as for convenience of description, meridian and base lines were found necessary, and accordingly instituted and established by law. In later years, particularly since the act of reorganization in 1836, the General Land Office has had direct and full control of the survey. ing departments. The surveying service since the act of reorganization has taken rapid strides forward in the way of improving the system in all its branches, by the selection of the peaks of the highest mountains as initial points of base lines and meridians.

As the convergency of the meridians must exist, and it is impossible to make ordinary measurements mathematically correct, on account of the inequalities of the earth's surface, and the imperfection of instruments, it is not the practice, as in early times, to rely upon a single meridian and base line to check the surveys, but what are called guide meridians and correction lines or standard parallels have been instituted, which are all run as nearly as human skill can effect it upon true meridians and parallels of latitude.

This system, in perfect accordance with the sphericity of the earth, secures uniformity and beauty in our surveys, particularly over a large surface, which by any other method it would be impossible to attain.

The system adopted for guide meridians is to run them at convenient intervals, making offsets at each standard parallel equal to the convergency, which may be readily calculated and offsetted, even in advance of the survey of the standard parallels. Those parallels are run from the meridians and guide meridians, upon true parallels of latitude; one for every four or five townships in the high latitudes, as in Oregon and Washington, and from six to ten townships in the lower latitudes, while a set of township and section corners of the legal width, of six miles for each township, and one mile to each section, are marked and established thereon, without reference to the closing lines and corners of the townships and section lines south of the parallel, so as to take up and thus arrest the convergency of the meridional lines of the surveys, inevitable in`running from one standard parallel to the next succeeding one.

These delicate and widely extended operations require not only a theoretical knowledge of astronomical science, but also a practical acquaintance with all the instruments employed in field operations by the surveyors general, who have the direct control of them.

Among the most important surveying duties is the marking in the field of the lines and corners of the surveys in a distinct and durable manner.

These marks, when identified as the originals, placed there by the sworn deputy surveyor of the United States, constitute in fact the survey, taking precedence over field-notes, official plats, or any like evidence, controlling all future proceedings in resurvey, and respected accordingly in proceedings affecting title before the courts of the country.

The surveying laws and our system presuppose that occupants and others desiring to obtain titles from the government are to have every facility in selecting and taking possession of the tracts they may purchase, and that in conforming their improvements to the marks they may find on the grounds, they may do so with the full assurance of their correctness, and that they cannot be disturbed by any future surveying operations.

Hence by the second section of the act of February 11, 1805, the corners and boundaries returned by the surveyor general are confirmed, and required to be taken and considered as the true corners and boundaries, and of these the fieldnotes and plats are merely the recorded description.

EXTENSION OF SURVEYS.

This system, so complete in itself, so simple and certain in fixing the lines upon the earth's surface, not only of town lots, but of agricultural lands, from 640, 320, 160, 80, and 40 nere tracts, has accomplished its work in Ohio, Indiana, Illinois, Michigan, Wisconsin, Iowa, Missouri, Arkansas, Mississippi, Alabama, and nearly so in Louisiana and Florida.

In those States are to be found climate, soil, and products equal to the wants and comforts of civilized man—cercals, esculents, and fruits in abundance, in the higher and in the middle latitudes, with the addition of the staples, tobacco and corn; while still further south are the cotton fields and sugar-cane, the orange, citron, and lemon.

Although the lines of the public surveys have been thus established, the system has yet further to advance upon the fields of Minnesota, northern and southern Dakota, in Montana, Kansas, Nebraska, Colorado, the Territories of New Mexico, Arizona, Utah, Idaho, Washington, and in the three great States, Nevada, Oregon, and California.

The progress made in those regions is as follows:

MINNESOTA.

In consideration of increased immigration to that State, secking the rich agricultural regions in the western and southwestern parts of the same, it was determined that a large portion of surveys should be established in those directions; contracts to this end having been made for nearly the whole amount of the appropriation by act of April 7, 1866.

The field-work embraces 509,743 acres, nearly half of which is on Sioux or Dakota land, south of the Minnesota. The surveyed area of the Indian tracts, with the quantity covered by the previous year, equals nearly four hundred thousand acres, which are to be appraised and sold pursuant to the act of 3d of March, 1863, for the benefit of the Indians.

Contracts requiring the $15,000 appropriated by act of 7th April, 1866, have been entered into by the surveyor general for the survey of the region in southwestern Minnesota adjoining the western boundary of the State and yet north of the Minnesota river and east of the Big Stone lake.

During the period which has elapsed from the beginning of the service in Minnesota to the present time, there has been surveyed in that State an aggregate of one thousand one hundred and eighteen townships, being two-fifths of the whole area of the State.

DAKOTA.

In Dakota the standard parallels, townships, and subdivisions have been extended within the Sioux Indian reservation, west of Big Stone lake, and so as to enclose a small northern bend of that reservation falling within the Minnesota line, the aggregate of the surveys there being equal to four hundred and twenty miles, embracing fourteen townships, containing a total of one hundred and fifteen thousand one hundred and eight acres of the Sioux or Dakota Indian lands.

It is reported that immigration is rapidly setting into the Territory from the eastern, middle, and western States, and from foreign countries. The surveyor general has therefore been directed to apply the $15,000 appropriated last session to such lauds fit for agricultural purposes as may be required for actual settlers.

MONTANA.

Montana forms part of the Dakota surveying district, and is remote from the seat of the surveyor general's office. In consideration of this fact, and of

the unsettled condition of the plains, growing out of Indian incursions, it has been deemed proper to defer surveys in that Territory until the ensuing season.

KANSAS AND NEBRASKA.

All surveys ordered under the appropriation of July 2, 1864, have been completed, while those under act of 7th April, 1866, are required to embrace localities along the Pacific railroad.

Immigration in excess of previous years is reaching different parts of Kansas and Nebraska, the advancing column being supplied with means, stock and implements for the establishment of permanent and substantial homes. The fertility of the country within the boundaries of the Osage and the Cherokee neutral limits has attracted settlers, who have learned with satisfaction of the prompt measures adopted by the government for the extension of the surveys, Contracts for which have been entered into by the department in conformity to recent treaties, the service amounting to $82,000, with $8,000 for the survey of Omaha reservation, in Nebraska.

The work of both branches of the Pacific railroad, it is understood, is rapidly and satisfactorily progressing, a recent act of Congress having allowed the southern branch to run up the Smoky Hill, while the northern branch is speedily advancing towards the mountains, having reached near to Fort Kearney.

The public lines established during the last fiscal year in Kansas embrace over one million one hundred and seventy-eight thousand acres, and upwards of three hundred and ninety thousand eight hundred in Nebraska.

COLORADO.

During the last fiscal year, four hundred and twenty-four thousand nine hundred and thirty acres were surveyed in Colorado, about one-twentieth part at the expense of settlers, under the authority of the 10th section of the act of 30th May, 1862, and the residue at the cost of the government. These with previous surveys make an aggregate of this service in Colorado of one million six hundred and twenty-two thousand two hundred and fifty-one acres, all on the eastern slope of the Rocky mountains, while there are now in progress surveys of standard township and section lines equal to 2,000 lineal miles, at an estimated cost of $15,000, appropriated by act of April 7, 1866.

The south park of the Rocky mountains contains about 35,000 acres of arable land, and the richest placer diggings.

Residents are urging the necessity of establishing there the public lines, representing that a very large portion would be sold to actual settlers. As this locality is disconnected from the existing standard lines, and forty miles of rough mountain country separates it from those lines, the surveyor general suggests, on the score of economy, the establishment in the park of an independent base line for that part of Colorado.

In the middle park it is reported that ten miles of the extension of the base line already established to the summit of the mountains will bring it to the head of the park. The wagon road over the range of mountains separating the agricultural regions of the western slope from the mining of the eastern has been completed, which with the overland road makes a passible wagon route from Denver to Salt Lake City, a distance of one hundred and fifty miles shorter than the former route.

The completion of this road to the Grand river it is believed will lead to the immediate occupation of the agricultural lands of the middle park, and the valleys of the Graud, White, and Bear rivers.

The surveyor general estimates the quantity of land under cultivation to be one hundred thousand acres; that one-half of the population of thirty-five thousand are engaged directly or indirectly in agricultural pursuits; that the

area of arable land is equal to four millions of acres; that the immigration of farmers during last year was of a class of people consisting of permanent settlers, the farming interest keeping pace with the wants of the population, and that a large surplus of all the necessaries of life is the anticipated produc tion of the present year.

The mineral and other resources of Colorado, particularly the product of gold, now on the increase, and of silver, copper, iron, petroleum, coal, and timber, are fully described in the interesting report of the surveyor general.

NEW MEXICO.

No field operations have been prosecuted in that Territory during the last fiscal year, on account of the hostility of the Indians. The personnel of the office, the surveyor general and translator, maintain the organization of the surveying service, translations having been made of a number of Spanish documents on file in the surveyor general's office relating to foreign titles.

Contracts have been made by the surveyor general for the survey of the confirmed private claims of San Pedro and Cañon del Agua, the expenses of the field operations and office work to be paid by the claimants, as the law directs. The surveying department proposes the extension of the public surveys on the waters of the Bonito, Ruidaso, and Hondo rivers, and in the valley of the Tularosa, south of Fort Stanton, where settlements are reported to exist, and also in the direction of Fort McLane, Gila, and Mimbres rivers.

It is of the first importance to the interests of the government, and of individuals claiming under Spanish and Mexican titles, that authority by iaw be delegated for the early and final adjustment of all claims in New Mexico and Arizona. This may be done either by delegating power to the local officers to hear and determine both as to the validity of the grant and the locus, subject to the final decision of the department, or by referring all such claims, under proper limitation as to time for filing and prosecuting, to the judiciary for adjustment, so that titles not valid under treaty may be forever barred in law and equity, and all valid may be confirmed and segregated from the public domain. A principle should be adopted in the suggested legislation to locate, with proper limitations as to quantity, according to the lines of the public surveys, all claims with undefined and uncertain limits, embracing not only past but future confirmations, and to fix a period within which parties shall hereafter apply and pay for the survey of the confirmation, in default of which the boundaries shall be made to conform to the public surveys.

Under the law as it now stands, the surveyor general of New Mexico is required to receive, pass upon, and report his opinions for the final determination of Congress, his jurisdiction not, however, extending to the Gadsden tract.

It is not only proper that the line between New Mexico and Colorado should be run and established, in order that the land officers on either side may keep within their jurisdiction, but, in a public point of view, it is necessary the line of demarcation between New Mexico and Colorado should be permanently run and established.

Concurring in the views of the surveyor general of New Mexico in that respect, an estimate for the purpose, of $19,000, is submitted.

ARIZONA.

The surveyor general has been instructed to establish and survey the base, meridian, and other lines embracing settlements, Indian hostilities having hitherto arrested the service.

The mineral and agricultural resources of Arizona, it is reported, are largely developed, several quartz mills being in operation in the vicinity of Prescott, and copper mines found on Bill Williams river near the Colorado of the West.
