taxes, the trade, the manufactures, the strength, the weakness, the
government of the several countries which a man of sense travels through,
are the material points to which he attends; and leaves the steeples, the
market-places, and the signs, to the laborious and curious researches of
Dutch and German travelers.

Mr. Harte tells me, that he intends to give you, by means of Signor
Vicentini, a general notion of civil and military architecture; with
which I am very well pleased. They are frequent subjects of conversation;
and it is very right that you should have some idea of the latter, and a
good taste of the former; and you may very soon learn as much as you need
know of either. If you read about one-third of Palladio's book of
architecture with some skillful person, and then, with that person,
examine the best buildings by those rules, you will know the different
proportions of the different orders; the several diameters of their
columns; their intercolumniations, their several uses, etc. The
Corinthian Order is chiefly used in magnificent buildings, where ornament
and decoration are the principal objects; the Doric is calculated for
strength, and the Ionic partakes of the Doric strength, and of the
Corinthian ornaments. The Composite and the Tuscan orders are more
modern, and were unknown to the Greeks; the one is too light, the other
too clumsy. You may soon be acquainted with the considerable parts of
civil architecture; and for the minute and mechanical parts of it, leave
them to masons, bricklayers, and Lord Burlington, who has, to a certain
extent, lessened himself by knowing them too well. Observe the same
method as to military architecture; understand the terms, know the
general rules, and then see them in execution with some skillful person.
Go with some engineer or old officer, and view with care the real
fortifications of some strong place; and you will get a clearer idea of
bastions, half-moons, horn-works, ravelins, glacis, etc., than all the
