est is the sufficient or insufficient quantity of atmospheric moisture. A more minuteinvestigation of the influence of the weather upon vegetation shows that in the majorityof Chernoziom governments often two or three abundant showers falling at the right timemay assure a plentiful yield of the principal crops, while an absence of rain at criticalmoments, for example during the filling of the grain, is the cause of a more or less con-siderable failure. In general it may be averred that the more primitive the system offarming and the more continental the climate, the greater the variation of the harvests. In consequence of the fact that agricultural statistics in Russia have latterly maderemarkable progress under ever-improving methods of collecting data upon the harvests,it is impossible to institute a comparison of the yields over any considerable period of YEARLY DEVIATION IN PERCENTAGE OF THE MEAN YIE& O^gYEFOR A PERIOD OF 11 YEARS (1881-1891 l^^^V Chapter VI.

It is therefore impossible to arrive at any conclusion with an approximation to thetruth, whether these yields are increasing or diminishing. The same must be said ofvariation in crops. To form some idea on this subject there is but one way, namely, tocollect harvest data extending over a lengthened period and from as many estates aspossible. Calculations from the figures so obtained for each year will yield the materialupon which a judgment may be based. Such a labour has been undertaken for rye, byMr. Fortunatov, Professor of the Petrovsk Agricultural Academy, and by Mr. Grass. Thediagram prepared by them embracing the period from 1840 to 1889 is appended to thiswork. It shows that the yield is on the whole increasing, while the changes in the har-vests are at the same time diminishing. It must however be observed that this di
