acre. The yields were nearly identical in each case, being 

 at the rate of 20 tons of green material to the acre (har- 

 vested September 3). On another twentieth-acre plot the 

 seed was drilled in at the rate of 15 pounds to the acre, and 

 a yield of 19 tons to the acre was secured. This plot, how- 

 ever, was very weedy, and it was not possible to separate the 

 weeds >from the sorghum before weighing the crop. It is 

 evident that when so^ai broadcast (which appeared to be 

 the most economical way for forage purposes) much less 

 seed is required to the acre than is ordinarily recommended. 

 It is intended to repeat these trials with smaller quantities 

 of seed. 



Alfalfa. — Observations have been continued on alfalfa 

 as a forage crop. A small piece seeded in the spring of 1905 

 came through the winter in good condition, and yielded 

 three crops the present season, aggregating 3.65 tons of hay 

 to the acre (figured at 15 per cent, moisture). Cuttings 

 were made June 25, August 3 and September 2. A growth 

 of six or more inches has been allowed to remain as a mulch 

 during the winter. 



A second piece, one-sixth of an acre in area, on which 

 alfalfa had been for two years previously, but which had 

 run out, was plowed in the spring of 1906, manured at the 

 rate of 6 cords to the acre, limed with burnt lime at the rate 

 of 1 ton to the acre, a fine seed bed made, and seeded with 

 seed procured from.F. E. Dawley, Eayetteville, N. Y. (lo- 

 cally known as Stillwell seed), and a light seeding of oats 

 (% bushel to the acre). The seed came up well, and the 

 combined alfalfa and oats were cut during July for forage. 

 A second cutting was made in September. A third growth 

 of six inches has been left as a mulch. It remains to be seen 

 if this piece as well as the other above mentioned will with- 

 stand the present winter, and continue to grow without being 

 replaced by clover and grasses. A fuller report will be made 

 later. 



Learning v. Pride of the North Corn. — The comparative 

 values of these two standard varieties are being studied, to 

 ascertain if one has any particular advantage over the other 

 for grain and silage purposes. Accurate determinations of
