AGRICULTURE AND HORTICULTURE. 189 



As was shown in Bulletin No. 37 of this station, this is more 

 proof that crimson clover does not withstand our winter cli- 

 mate. Its main value is in its growth of the first season, and 

 it must therefore be considered as an annual with us. As a 

 crop for seeding in fruit plantations, simply for the additional 

 food value of the plantation and to keep the soil from wash- 

 ing during winter, it is valuable; but even here the seeding 

 should be done early in August in order to obtain desirable 

 results. Comparing crimson clover with the medium red 

 variety, there seems to be little if any gain in its use. If the 

 medium red and alsike are mixed, our experience shows that 

 because of their ability to withstand the winters, while in all 

 other respects they answer the same purpose, they are equally 

 valuable if not more so. 



Thomas Slag vs. Redoxdite as a Fertilizer. 



A comparative test of these two phosphoric acid fertilizers 

 was undertaken in the late spring of 1897, upon land seeded 

 to grass. The nitrogenous and potash fertilizers were ap- 

 plied in equal quantities on both plots, and consisted of 80 

 pounds of nitrate of soda and 400 pounds of kainit per acre. 

 The Thomas slag was used at the rate of 160 pounds per acre 

 on plot 1. Plot 2 was equally divided. Eaw redondite was 

 used on one half at the rate of 80 pounds per acre, and roasted 

 redondite at the rate of 40 pounds per acre on the other. 



The barley used as a nurse crop was cut on September 7 

 with the following yields: Thomas slag plot, at the rate of 

 1,312 pounds, raw redondite, 1,520 pounds, and roasted redon- 

 dite, 1,424 pounds per acre. The present season these same 

 plots were weighed at haying time, with the following results: 

 Thomas slag, 3,704 pounds, raw redondite, 4,320 pounds, and 

 roasted redondite, 3,248 pounds per acre. 



In each year, as is shown in the data, the raw redondite 

 gave the greatest yield. Of the other two, the roasted redon- 

 dite exceeded the Thomas slag by 112 pounds per acre in the 

 first year, while in the present season it was reversed, the 

 Thomas slag yielding 456 pounds per acre more than the
