ties of nitrogenous fertilizers, which are carefully- 

 excluded from ordinary varieties, can be applied with 

 safety to the Improved Vilmorin, as a great number of 

 experiments has shown that this can be done without 

 serious deterioration in the quality of the sugar and 

 with a considerable increase in weight. From thou- 

 sands of analyses it has been established that the per- 

 centage of sugar that can be obtained with this variety 

 is about sixteen. Its average yield under favorable 

 conditions can be stated to be from 12 to 16 tons 

 per acre." 



We may add that late rains, so much to be dreaded 

 in many countries, appear to have far less influence on 

 the Vilmorin Improved than on most beets. On 

 account of the extensive way in which Vilmorin 's 

 Improved is cultivated, the seed can be purchased 

 at ten cents per pound. Thousands of analyses show 

 that it can be depended upon to furnish 15 per cent, 

 sugar and a yield of 15 tons of beets to the acre. The 

 other varieties put out by this firm, such as French 

 Very Rich, Red Top, Early Red Skin, Gray Top, etc., 

 were very fully described in the author's work, "The 

 Sugar Beet," and no further mention of them need be 

 made here. Some of these have precocity, while others 

 are noted for their keeping qualities. M. Vilmorin 

 thinks that beets require a deep loam, or even a clay 

 soil, if not too deep. A clayey subsoil is very desirable 

 if it be covered with at least 15 inches of surface soil. 

 He emphasizes the fact that thorough drainage is 

 imperatively demanded. It should be added, that the 

 special agents for supplying Vilmorin's sugar-beet 

 seeds to the sugar-beet industry in the United States, 

 are Willett & Gray, 91 Wall street. New York.
