clover is desired. These may take the place of the slag meal and potash 

 mixtures which have been suggested. The ashes will supply a large 

 amount of lime as well as potash and phosphoric acid. Fine-ground 

 bone is also under many conditions a useful fertilizer, especially in 

 mixture with potash, for permanent mowings where clover is desired. 

 The experiment station plots have been several times referred to. The 

 9-acre field is divided into three nearly equal plots. Each of these is 

 treated as follows : fiirst year, barnyard manure at the rate of 16,000 

 pounds per acre, applied in the fall ; second year, wood ashes at the 

 rate of 1 ton per acre, applied in early spring; the third year, fine- 

 ground bone 400 pounds per acre, and muriate of potash 200 })ounds, 

 mixed and applied in early spring. Each year all three systems of 

 manuring are re]i)resented. Our average crops under this system have 

 been heavy, having amounted, as has already been stated, to 6,600 

 pounds jJer acre. 



Reseeding Permanent Mowings. — That it pays occasionally to reseed 

 permanent mowings is made very evident b}- the results obtained in 

 Amherst in the season of 1903. A portion of each of two plots in the 

 station mowings was plowed and reseeded in the summer of 1902, as 

 already described One of these jjlots was the one top-dressed in 1903 

 with wood ashes. The yield on the portion not reseeded was at the rate 

 of 6,243 pounds per acre; on the reseeded portion the yield was at the 

 rate of 8,546 j^ounds. On the plot manured with barnyard manure the 

 yield on the portion not reseeded was at the rate of 5,642 pounds per 

 acre; on the reseeded portion it was at the rate of 10,(t02 pounds per 

 acre. The manure used on the reseeded portion of this plot was har- 

 rowed in at the time the seed was sown. The balance of the plot was 

 top-dressed late in the fall, as usual. 



Top-dressing for Rowen. — Experiments extending over several years 

 in Amherst indicate a probable profit from the ajjplication of a moderate 

 top-dressing of nitrate of soda immediately after the removal of the first 

 crop. This should of course be made only on mowings where the prod- 

 uct is almost exclusively grasses. Top-dressing with nitrate of soda 

 for clover would be a mistake, as this, as already stated, should get its 

 nitrogen from the air The quantity of nitrate likely to prove useful 

 will usually vary between about 150 and 200 pounds per acre.
