yet giveu no results uniform and everywhere applicable. 

 Such results we can only expect from a study of those laws 

 which may be deduced from the artificial cultivation of the 

 beet in special liquids. 



And yet it is in no contradiction of these facts when we 

 advise the beet culturist to keep up constant experiments 

 with fertilizers upon different sells. It is in such cases Only 

 necessary to determine the particular form and quantity of 

 manure which under the peculiar local conditions gives the 

 best returns. And in many cases some particular form of 

 manure will prove the best, but the power to produce a safe 

 and invariable influence upon the crop will only seldom be 

 attained. The effect of those factors over which we have no 

 power, climate and weather, are of infinitely greater in- 

 fluence than the small alterations which we can produce by 

 ihe augmentation, deterioration, or maintenance of good 

 ■condition of soil within the circumscribed limits of artificial 

 fertilization." 



" Experience has taught that those beets which are raised 

 upon fields manured with fresh — especially stable -manure 

 are less suited for manufacturing purposes. On this account 

 the rule has long been established that the manure should 

 not be applied directly to the beets, but to some other pre- 

 vious crop, or, that beets should be cultivated as the 2ad or 

 3rd in a series of rotation. Unfortunately this rule, most 

 important to the manufacturer, was not so generally observed 

 in earlier times as it should have been, so that very often on 

 account of heavy manuring large crops were obtained, but 

 at the expense of the sugar, or quality of the juice. 



This rule is especially applicable to stable manure, and 

 that from cess-pools ; less so to the so-called " artificial ferti- 

 lizers" which, when they are not employed directly in too 

 great quantities, are followed by fewer injurious effects.
