Here we find the fertilizers have apparently produced a 

 moderate increase in crop. The differences between them 

 are far less marked than in the case of most of the other 

 crops grown this year. The nitrate of soda appears to have 

 been the best source of nitrogen for the cabbage. 



Early Maine' Potatoes. — The seed planted was grown in 

 the State of jNIaine. It was treated with corrosive sublimate 

 solution, for prevention of scab, and sun-sprouted. Before 

 planting, the tubers were cut to pieces with two eyes each. 

 Three rows per plot (4 on Plot 0) were grown. The seed 

 was planted on May 9 in rows 3 feet apart, the pieces being 

 dropped 1 foot apart in the rows. Ordinary thorough cult- 

 ure was given until the vines covered the ground. The 

 vines were sprayed with Bordeaux mixture (first on June 7) 

 to repel the flea beetle. They were sprayed with sufficient 

 frequency to keep the vines well covered with the mixture 

 until the middle of August, the last application being made 

 August 8. The Bordeaux mixture was applied nine times in 

 all, frequent re-application being necessary, on account of 

 the numerous heavy rains. The vines were slightly attacked 

 by blight about the middle of July ; but later in August new 

 shoots were thrown out from the axils of the lower leaves, 

 making a healthy growth, which remained green until very 

 late in September. The tubers averaged large and smooth, 

 and showed very little rot when dug. A few weeks after 

 storing there were a few more decayed tubers. The yield 

 in pounds was as follows : —

 Plot 1,
