Your letter of November the 26th came to hand May the 14th; the books
some time after, which were all distributed according to direction.
The copy for the East Indies went immediately by a safe conveyance. The
letter of April the 28th, and the copy of your work accompanying
that, did not come to hand till August. That copy was deposited in the
Congressional library. It was not till my return here from my autumnal
visit to Monticello, that I had an opportunity of reading your work. I
have read it, and with great satisfaction. Of the first part I am less a
judge than most people, having never travelled westward of Staunton,
so as to know any thing of the face of the country; nor much indulged
myself in geological inquiries, from a belief that the skin-deep
scratches, which we can make or find on the surface of the earth, do not
repay our time with as certain and useful deductions, as our pursuits in
some other branches. The subject of our winds is more familiar to me.
On that, the views you have taken are always great, supported in their
outlines by your facts; and though more extensive observations, and
longer continued, may produce some anomalies, yet they will probably
take their place in this first great canvass which you have sketched. In
no case, perhaps, does habit attach our choice or judgment more than
in climate. The Canadian glows with delight in his sleigh and snow,
the very idea of which gives me the shivers. The comparison of climate
between Europe and North America, taking together its corresponding
parts, hangs chiefly on three great points. 1. The changes between heat
and cold in America are greater and more frequent, and the extremes
comprehend a greater scale on the thermometer in America than in Europe.
Habit, however, prevents these from affecting us more than the smaller
changes of Europe affect the European. But he is greatly affected by
ours. 2. Our sky is always clear; that of Europe always cloudy. Hence a
greater accumulation of heat here than there, in the same parallel. 3.
