one pound of semilla of mealy cochineal placed on nopals in the month of October, in the month of January yields a harvest of 12 pounds of mother cochineals, leaving sufficient semilla. on the plant, that is to say beginning the harvest only when the mothers have already produced the half of their young. This new semilla again produces till the month of May 36 pounds. At Zimatlan and other villages of Misteca and Xicayan they scarcely reap more than three or four times the quantity of cochineal If the south wind which is very pernicious to the growth of the insect has not blown long, and the cochineal is not mixed with tlasole, that is to say with the spoils of the winged males, it loses only two thirds of its weight when dried in the sun.

sown.

The two kinds of cochineal (the fine and the. wild) appear to contain more of the colouring principle in temperate climates, especially in regions where the mean temperature of the air is 18 or 20 centigrade degrees*. As to the wild cochineal we found it in abundance in the most opposite climates, in the mountains of Riobamba, at 2900 metrest of absolute elevation, and in the plains of the province of Jaen de Bracamoros, under a burning sky, between the villages of Tomependa and Chamaya.

Around the town of Oaxaca, and especially near Ocotlan there are plantations (haciendas) which contain from 50 to 60,000 nopals planted in lines like pites or magueys de pulque. The greatest part of the cochineal which is employed in commerce is, however, produced in small nopaleries belonging to Indians of extreme poverty. The nopal is seldom allowed to grow higher than 12 decimetres* in order that it may be the more easily cleared of the insects which devour the cochineal. The varieties of the cactus which are roughest and most prickly are even preferred, because these arms serve to protect the cochineal from flying insects; and the flower and fruit are carefully cut to prevent these insects from depositing their them.

The Indians who cultivate the cochineal and who go by the name of nopaleros, especially those who live round the town of Oaxaca, follow a very ancient and a very extraordinary practice, that of making the cochineal travel. In that part of the torrid zone, it rains in the plains and vallies from May to October, while in the chain of neighbouring mountains called Sierra de Istepeje, the rains are only frequent from December to April. In place of ing the insect in the rainy season in the interior of their huts, the Indians place the mother-co

chineals, covered with palm-leaves by beds in baskets made of very flexible claspers. These baskets (canastos) are carried by the Indians on their backs as quickly as possible to the mountains of Istepeje, above the village of Santa Catalina, at nine leagues distance from Oaxaca. The mother cochineals produce their young by

the way. On opening the canastos they are found full of young coccus, which are distributed on the nopals of the sierra. They remain there till the month of October when the rains cease in the lower regions. The Indians then return to the mountains in quest of the cochineal for the purpose of replacing it in the nopaleries of Oaxaca. The Mexican in this way withdraws the insects from the pernicious effects of the humidity in the same manner as the Spaniard travels with his merinos from the cold.

At the period of the harvests the Indians kill the mother cochineals, which are collected on a wooden plate called chilcalpetl. by throwing them into boiling water, or heaping them up by beds in the sun, or placing them on mats in the same ovens of a circular form (temazcalli) which are used for vapour and hot air baths of which we have already spoken*. The last of

* See vol. ii. p. 349. M. Alzate who has given a good plate of the temazcalli (Gazeta de Literatura de Mexico. T. iii. p. 252.) asserts that the ordinary heat of the vapour in which the Mexican Indian bathes himself is 66° centigrade. (150° of Fahrenh. Trans.)

these methods, which is least in use, preserves the whitish powder on the body of the insect, which raises its price at Vera Cruz and Cadiz. Purchasers prefer the white cochineal, because it is less subject to be fraudulently mixed with parcels of gum, wood, maize, and red earth. There exist in Mexico very ancient laws (of the years 1592 and 1594) for the prevention of the falsification of cochineal. Since 1760 they have even been under the necessity of establishing in the town of Oaxaca a jury of veadores who examine the bags (zurrones) previous to their being sent out of the province. They appoint the cochineal exposed to sale to have the grain separated, that the Indians may not introduce extraneous matter in those agglutinated masses called bodoques. But all these means are insufficient for the prevention of fraud. However, that which is practised in Mexico by the tiangueros or zanganos (falcificadores) is inconsiderable in comparison of that which is practised on this commodity in the ports of the Peninsula, and in the rest of Europe.

To complete the view of the animals of New Spain we must bestow a rapid glance on the pearl and whale fisheries. It is probable that these two branches of fishery will one day become an object of the very highest importance to a country possessed of a length of coast of more than 1700 marine leagues. Long before

the discovery of America, pearls were in great estimation among the natives. Hernando de Soto found an immense quantity in Florida, particularly in the provinces of Ichiaca and Confachiqui, where the tombs of their princes were ornamented with them*. Among the presents made by Montezuma to Cortez before his entry into Mexico, which were sent by Cortez to the emperor Charles V., there were necklaces set with rubies, emeralds, and pearls†. We know not whether the Aztec kings received any part of these pearls by means of trade with the barbarous and wandering tribes who frequented the gulf of California. It is better ascertained that pearls were fished by their orders, on the coast which extends from Colima, the northern boundary of their empire, to the province of Xoconochco or Soconusco, and particularly near Tototepec, between Acapulco and the gulf of Tchuantepec and in Cuitlatecapan. 'The Incas of Peru set a great value on pearls; but the laws of Manco-capa prohibited the Peruvians from exercising the calling of diver, as not very beneficial to the state and dangerous to those who follow it.
