MANURES. 135 



Four lots ill No. 3 were manured with clear meadow mud, 

 eiglity-three pounds of Coe's super-phosphate of lime being 

 added to each cord of mud, and well worked over ; 72^*^2 cubic 

 feet to each lot. Lot No. 5 had no manure. 



April 28th, 1862, the three different kinds of manure were 

 applied to lot No. 1 in each range, and the whole field ploughed 

 eight and one-half inches deep. On the 29th, lot No. 2 in each 

 range was manured with the different kinds of composts, and 

 the whole field again ploughed four inches deep. On the 30th, 

 lots No. 3 were manured in the same manner, and the whole 

 sowed with jura wheat, one and one-half bushels per acre, 

 soaked twenty-four hours in brine so strong that the salt had 

 not all dissolved. The wheat was dried for sowing by adding 

 one peck of Timothy, one-half bushel of red top and five 

 pounds of clover to each bushel and a half of wheat, and mixing 

 them well. The whole was harrowed in faithfully with what is 

 here called the Pepperell harrow, and the entire field smoothed 

 by drawing over it a slab, with the rounded side down. 



May 3d, the compost was applied to lots No. 4, the rain 

 preventing me from applying it sooner. Lot No. 5 had no 

 manure. 



The wheat came up, and looked well until the latter part of 

 July, when I discovered, at a distance of forty rods from it, a 

 change in its appearance. I found, on examination, the heads 

 of the wheat literally covered with the midge, or a kind of 

 aphis, which destroyed the whole crop in a few days, turning 

 the straw almost black and nearly worthless, except for manure ; 

 but, desiring to obtain for you all the information in my power, 

 I cut the straw on each lot, and having dried it well, weighed 

 it correctly. Harvested August 5th, 1862. Annexed is the 

 result in pounds and decimals of a pound : —
