‘Hendon, Middlesex: Sept. 1794.

‘Dear Sir,—Permit my ignorance to draw upon your science on an occasion that happens just now to be a very material one to me. I have a sort of floating recollection of a calculation, so circumstanced, either in point of authority or argument, as to carry weight with it, in which the total value of the landed property in this country (Scotland, I believe, included) was reckoned at a thousand millions, and that of the movable property at either a thousand millions or twelve hundred millions. Public debt did not come, I think, at least, it ought not to come, into the account; it being only so much owned by one part of the proprietors of the two thousand or the two thousand two hundred millions to another.

‘Upon searching your book on France, which was the source from whence I thought I had taken the idea, I can find no calculation of the value of the movable property, nor even of the immovable in an explicit form; on the contrary, in the instance of the immovable, I find suppositions with which any such estimate appears to be incompatible. The land tax at four shillings, I find, you suppose, were it to be equal all over the country, would be equivalent to as much as three shillings, on which supposition the rental (the tax of four shillings producing no more than two thousand millions) would amount to no more than 13,000,000l. nor consequently the value, at so many years’ purchase, say twenty-eight, to more than three hundred and sixty-four millions; or at thirty, to three hundred and ninety millions; to which, in order to complete the calculation of the landed property of Great Britain, that of Scotland would have to be added.

‘The population of the three kingdoms you reckon in two places at eleven millions; but in another place at fifteen. Is the latter a slip of the pen? or, in the two former places, was only two kingdoms (England and Scotland) in your view, though three are mentioned? A circumstance that seems to favour the latter supposition is, that the population of Ireland is well known (if I do not much misrecollect) from recent and authentic sources to be a little more than four millions; and as Scotland turns out to contain a million and a half, this would leave nine and a half millions for England, which, I should suppose, would quadrate in round numbers with Mr. Howlett’s calculations, to which we refer; a book which, from forgetfulness, I have never made myself master of, and to which, being in the country, I have no speedy means of recurring.

‘Now what I wish for is as follows: (1) a calculation (or, I should rather say, the result) of the value of the landed property of Great Britain reckoned at [so many] years’ purchase, two prices—a peace price and a war price—could they be respectively of sufficient permanence to be ascertained, would be of use.

‘(2) A calculation of the value of the personal, i.e. immovable property of Great Britain.

‘(3) The amount of the population of Great Britain.

‘What I am a petitioner for is the benefit of your judgment and authority upon the three several subjects; by reference, if there be any other person’s calculation that you are satisfied with; otherwise from your own notes; and, in either case, a word or two just to indicate the sources from which they are taken would be an additional help and satisfaction.

‘The occasion of the trouble I am attempting to give you I expressly forbear mentioning; not only for want of space and time, but more particularly that it may be impossible, and might, upon occasion, be known to be impossible, that the response of the Oracle should have received any bias from the consideration of the purpose for which it was consulted.

‘I am, dear sir, with never failing esteem and regard,
