Էջ 298 - The internal shallowness of the boat, from the gunwale down to the platform, the convexity of the form, and the bulk of cork within, leave a very diminished space for the water to occupy ; so that the life-boat, when filled with water, contains a considerably less quantity than the common boat, and is in no danger either of sinking or overturning.
Էջ 298 - LifeBoat, from her peculiar form, may be rowed ahead, when the attempt in other boats would fail. Boats of the common form, adapted for speed, are of course put in motion with a small power, but, for want of buoyancy and bearing, are over-run by the waves and sunk, when impelled against them; and boats constructed for burthen meet with too much resistance...
Էջ 29 - The innundations have the same effect here as the periodical overflowings of the Nile in Egypt, and render the country one of the most fruitful in the world. In many parts the land produces three crops of grain in the year. All the fruits of India are found here in the greatest perfection, with many of those of China. No country in the East...
Էջ 302 - Boat, when manned, the person who steers her should be well acquainted with the course of the Tides, in order to take every possible advantage: the best method, if the direction will admit of it, is to head the Sea. The Steersman should keep his eye fixed upon the Wave or Breaker, and encourage the Rowers to give way, as the Boat rises to it; being then aided by the force of the Oars, she launches over it with vast rapidity, without shipping any Water.
Էջ 54 - we subdue nature, and derive aid and comfort from the elements of earthquakes.f The first engine that Mr.
Էջ 299 - Two wheels of nine feet diameter, with a moveable arched anis> and a pole fixed thereto for a lever, have been constructed. The boat is suspended near her centre, between the wheels under the axis; toward each extremity of which is an iron pin, with a chain attached. When the pole is elevated perpendicularly, the upper part of the axis becomes depressed, and the chains being hooked to eye-bolts on the inside of the boat, she is raised with the utmost facility, by means of the pole, which is then...
Էջ 53 - When we contemplate the enlarged extent of his views, the wide and rapid circulation of his improvements and discoveries in the most important branches of art, and the numerous and honourable connections which he...
Էջ 29 - Cochin-China are called Moys, and are the people which inhabit the chain of mountains which separate it from Cambodia. To these strongholds they were driven when the present possessors invaded the country. They are a savage race of people, very black, and resemble...
Էջ 32 - China, and under their direction manufactories carried to as great a degree of perfection as in China itself. The intercourse between Japan and Cochin China might be renewed and we might participate in a trade, for many years monopolized by the Dutch. An advantageous trade might be carried on with the Philippine Islands, and Madras and Bengal goods introduced amongst them by means of the junks for...
Էջ 302 - Oars, she launches over it with vast rapidity, without shipping any Water. It is necessary to observe, that there is often a strong reflux of Sea, occasioned by the stranded Wrecks, which requires both dispatch and care in the people employed, that the Boat be not damaged.
