These instances are quite enough, I should imagine, to satisfy ordinary curiosity on this point; but professional men ought not to be contented till they have investigated all branches of this important topic; including that elegant and very useful episode, the land and sea breezes of all hot climates, and Horsburgh’s East India Directory, which I have quoted above so frequently, is by far the best authority with which I am acquainted on these subjects.  At the same time, I must not omit to do justice to a beautifully-written and accurate Essay on Winds and Currents, by that Prince of all Voyagers, Old Dampier; who, with means far more circumscribed than most of his successors, has contrived to arrange and condense his information in such a way as not only to render it available to practical men, but to make it intelligible and interesting to every class of readers.[4]

FOOTNOTES: 

[3] It is necessary to note here that these questions have been examined since Captain Hall wrote, by Commander Maury, late secretary to the American navy, in the true analytical spirit, and immense progress made in our knowledge of these winds by the mass of practical observations on the subject made by practical navigators, and published under his directions.—­Ed.

CHAPTER VII.

Progress of the voyage.

Let people say what they please of the fine bracing weather of a cold climate, I have never seen any truth-speaking persons who, on coming fairly to the trial, did not complain of a cold frosty morning as a very great nuisance, or who did not cling eagerly to the fire to unbrace themselves again.  For my own part, I have always delighted in the relaxation caused by hot weather; and, accordingly, I have very seldom, if ever, felt the weather disagreeably warm, even in India, especially when sailing on the open sea, or enjoying the free range of a wide country, under awnings and bungaloes, or stretched in a palanquin, or shaded by an umbrella on the back of an elephant.  Soldiers and sailors, whose duty exposes them at all hours, either on a march or in boats, are often struck down by the heat, and sigh with all their hearts for the bracing frosts of higher latitudes.  But those who have the means of bringing to bear on their comforts the innumerable contrivances which the ingenuity of wealth has devised in the East, indeed, make its climate not only bearable, but one of the most enjoyable in the world.
