"The public services to which the yeomanry were bound were not less arbitrary than the private ones. To make and maintain the high roads, a servitude which still subsists, I believe, every-where, though with different degrees of oppression in different countries, was not the only one. When the king's troops, when his household or his officers of any kind passed through any part of the country, the yeomanry were bound to provide them with horses, carriages, and provisions, at a price regulated by the purveyor. Great Britain is, I believe, the only monarchy in Europe where the oppression of purveyance has been entirely abolished. It still subsists in France and Germany.
The public taxes to which they were subject were as irregular and oppressive as the services. The ancient lords, though extremely unwilling to grant themselves any pecuniary aid to their sovereign, easily allowed him to tallage, as they called it, their tenants, and had not knowledge enough to foresee how much this must in the end affect their own revenue. The taille, as it still subsists in France, may serve as an example of those ancient tallages. It is a tax upon the supposed profits of the farmer, which they estimate by the stock that he has upon the farm. It is his interest, therefore, to appear to have as little as possible, and consequently to employ as little as possible in its cultivation, and none in its improvement. Should any stock happen to accumulate in the hands of a French farmer, the taille is almost equal to a prohibition of its ever being employed upon the land. This tax, besides, is supposed to dishonour whoever is subject to it, and to degrade him below, not only the rank of a gentleman, but that of a burgher, and whoever rents the lands of another becomes subject to it. No gentleman, nor even any burgher who has stock, will submit to this degradation. This tax, therefore, not only hinders the stock which accumulates upon the land from being employed in its improvement, but drives away an other stock from it. The ancient tenths and fifteenths, so usual in England in former times, seem, so far as they affected the land, to have been taxes of the same nature with the taille."
