Rh has given an additional stimulus to the spirit of improvement In some other countries, and particularly in France, the improvement of agriculture gains ground still more decidedly upon population, because though agriculture, except in a few provinces, advances slowly, population advances still more slowly, and even with increasing slowness; its growth being kept down, not by poverty, which is diminishing, but by prudence.

Which of the two conflicting agencies is gaining upon the other at any particular time, might be conjectured with tolerable accuracy from the money price of agricultural produce (supposing bullion not to vary materially in value), provided a sufficient number of years could be taken, to form an average independent of the fluctuations of seasons. This, however, is hardly practicable, since Mr. Tooke has shown that even so long a period as half a century may include a much greater proportion of abundant and a smaller of deficient seasons than is properly due to it. A mere average, therefore, might lead to conclusions only the more misleading, for their deceptive semblance of accuracy. There would be less danger of error in taking the average of only a small number of years, and correcting it by a conjectural allowance for the character of the seasons, than in trusting to a longer average without any such correction. It is hardly necessary to add, that in founding conclusions on quoted prices, allowance must also be made as far as possible for any changes in the general exchange value of the precious metals.
