Eilglish liay and corn meal, is very unprofitable, because beets 

 are deficient in albumenoids, much more so than turnips, but 

 all roots can be used to the best advantage with poor hay and 

 straw, together with grain rich in albumenoids. This is so 

 because in poor hay and straw the per cent, of indigestible 

 organic matter is large, in all root crops it is small, and by 

 feeding them together, the per cent, of indigestible matter is 

 reduced ; and if care is taken to get the proportion of albu- 

 menoids and carbo-hydrates right, roots are profitable. This 

 shows us why it is that the English buy so much of the Ameri- 

 can oil meals. Their climate is well suited to turnip grow- 

 ing ; they feed turnips with their straw to get the proportion 

 of digestible matter right, and feed oil meal to get the pro- 

 portion of albumenoids right. Whether it is economy to 

 grow roots, depends upon what one has to feed with them. 



There are other branches of this subject which it would be 

 pleasant to follow, but space forbids. 



ORIGINATING NEW POTATOES. 



BY JAS. J. H. GREGORY, OF MARBLEHEAD. 



Since the general prevalence of the disease popularly known 

 as the "potato rot," which virtually annihilated some standard 

 varieties, and so seriously affected the health of others as to 

 render profit in their cultivation precarious, the public have 

 given great attention to the originating of new varieties, with 

 the object of obtaining in these a constitutional vigor that 

 should manifest itself in greater productive powers, better 

 quality of tuber, and greater capacity to withstand disease. 

 The result of these most laudable efforts has been to give, 

 within the past dozen years, thousands of new varieties of 

 potatoes. 



Among these about two dozen stand out prominently as
