The semi-elliptical arch has one recommendation yet unexamined:  we are told, that it is difficult of execution.  Why difficulty should be chosen for its own sake, I am not able to discover; but it must not be forgotten, that, as the convexity is increased, the difficulty is lessened; and I know not well, whether this writer, who appears equally ambitious of difficulty, and studious of strength, will wish to increase the convexity for the gain of strength, or to lessen it for the love of difficulty.

The friend of Mr. M——­, however he may be mistaken in some of his opinions, does not want the appearance of reason, when he prefers facts to theories; and that I may not dismiss the question without some appeal to facts, I will borrow an example, suggested by a great artist, and recommended to those who may still doubt which of the two arches is the stronger, to press an egg first on the ends, and then upon the sides.

I am, Sir, yours, &c.

SOME THOUGHTS ON AGRICULTURE, BOTH ANCIENT AND MODERN,

With an account of the honour due to an English farmer[1].

Agriculture, in the primeval ages, was the common parent of traffick; for the opulence of mankind then consisted in cattle, and the product of tillage, which are now very essential for the promotion of trade in general, but more particularly so to such nations as are most abundant in cattle, corn, and fruits.  The labour of the farmer gives employment to the manufacturer, and yields a support for the other parts of the community:  it is now the spring which sets the whole grand machine of commerce in motion; and the sail could not be spread without the assistance of the plough.  But though the farmers are of such utility in a state, we find them, in general, too much disregarded among the politer kind of people in the present age; while we cannot help observing the honour that antiquity has always paid to the profession of the husbandman; which naturally leads us into some reflections upon that occasion.

Though mines of gold and silver should be exhausted, and the specie made of them lost; though diamonds and pearls should remain concealed in the bowels of the earth, and the womb of the sea; though commerce with strangers be prohibited; though all arts, which have no other object than splendour and embellishment, should be abolished; yet the fertility of the earth alone would afford an abundant supply for the occasions of an industrious people, by furnishing subsistence for them, and such armies as should be mustered in their defence.  We, therefore, ought not to be surprised, that agriculture was in so much honour among the ancients; for it ought rather to seem wonderful that it should ever cease to be so, and that the most necessary and most indispensable of all professions should have fallen into any contempt.

Agriculture was in no part of the world in higher consideration than Egypt, where it was the particular object of government and policy; nor was any country ever better peopled, richer, or more powerful.  The satrapae, among the Assyrians and Persians, were rewarded, if the lands in their governments were well cultivated; but were punished, if that part of their duty was neglected.  Africa abounded in corn; but the most famous countries were Thrace, Sardinia, and Sicily.
