No. 60. 5 acres Rivett WHEAT sown first week in October on 

 heavy clay soil overlying Boulder Clay, ploughed out of 35- 

 years-old grass. The herbage was very rough and poor, and the 

 surface covered with bushes. The land required draining. 

 It was ploughed in 1916 (skim coulter) to a depth of 6 inches, 

 all the rough glass being carefully buried; pressed with Cam- 

 bridge roller, and left till June. In hot weather the furrows 

 were reversed, then cross-ploughed and reversed. In August 

 it was stetched up into 8-foot stetches, cultivated, harrowed 

 three times, rolled down. The crop came away well, but was 

 injured by frost and looked very poor in spring. As soon as 

 the land was dry enough it w r as harrowed three times with a 

 heavy harrow. Wire worm attacked the crop, but the heavy 

 rolling prevented serious damage. Ultimately the crop thickened, 

 and promises well. Success attributed to careful cultivation and 

 fairly early sowing. The grower recommends that in breaking up 

 rough grass of this kind it is desirable to employ two ploughs, 

 one following the other. The first should plough a shallow 

 fui-row and the second should bury the surface with a 6-inch 

 furrow. 



The same grower broke up 5 acres in the same field in the 

 spring of 1915, and oats were sown in March. Crop very poor. 

 Winter beans sown in October and the crop was fair for the land 

 about 3 quarters per acre. WHEAT was sown in November, 1916, 

 and promises well. 



CAMBRIDGE (3 reports 2 successes, 1 failure). 



No. 61. BARLEY sown about May 8th on sandy soil ploughed out 

 of old grass in the beginning of May. Land turned over quite 

 flat to a depth otf 7 inches, rolled three times with heavy 

 Cambridge roller, and harrowed four times. Crop received 

 4 cwt. per acre of a manure containing superphosphate and 

 sulphate of ammonia. Result satisfactory, attributed to the 

 thorough consolidation of the land. The benefit of the manure 

 was marked. 



No. 62. 20 acres OATS sown on land ploughed in March (skim 

 coulter) out of 17-years-old heath overlying Chalk, to a depth of 

 4 inches ; twice rolled with heavy roller, harrowed four times, 

 seed drilled on the fresh furrow, harrowed twice. The growing 

 crop was horse-hoed. Wood pigeons did much damage, otherwise 

 the crop would have been most successful. 



No. 63. A field of 20 acres of similar (heath) land, broken up in 

 the previous ye<ar, was sown in 1916 with wheat, yielding 30 bushels 

 per acre, and in 1917 with BARLEY, which promises 32 bushels per 

 acre. The barley was dressed with 5 cwt. fish meal per acre. 



No. 64. OATS sown in clay loam soil on the Kirneridge Clay, 

 ploughed in March out of 28-years-old grass, twice rolled and 

 harrowed, seed drilled. Crop a failure, the primary cause being 

 want of consolidation. The soil was quite loose. Secondary causes 

 were drought and wireworm. On the headlands, where the land 

 had been trampled by horses, and in the open furrows, there was 

 a fair crop. 



HUNTINGDON (2 reports- 1 success, 1 failure). 



No. 65. 30 acres HARLEY sown in April, 1917, on land overlying 

 Boulder Clay. Ploughed in March, 1916, out of 20-years-old grass
