Report on the Field and Feeding Experiments at Woburn. 339 
similar experiments of last year. The composition of the 
turnips used was — 
Water 92-80 
•Albuminous compounds 0*77 
Sugar, woody fibre, &c 5 * 88 
Mineral matter (ash) 0 • 55 
100-00 
* Containing nitrogen -12 
The amount of nitrogen in the wheat-straw chaff was -77 per 
cent., equal to 4-81 per cent, of albuminous compounds. The 
duns was removed from the nits on November 13th, and left 
covered until January 24:th, 1883, when it was found to weigh 
33 cwt. 1 qr. 26 lbs. On to one-half of Plot 10, a quantity of 
dung, calculated to contain nitrogen equal to 100 lbs. of ammonia 
per acre, was applied, and double that quantity to one-half of 
Plot 11. 
The mineral manures were sown broadcast on February 16th, 
and the nitrogenous top-dressings on April 13th. November 
was wet and storm v, followed by frost and snow in the early part 
of December, after which milder weather set in, and the wheat 
began to appear above ground. In the beginning of January the 
wheat was growing well, any gaps in it being filled up this month. 
Heavy rains followed towards the close of January and com- 
mencement of February : 2-26 inches of rain having fallen in 
January, and -75 inch in the two first days of February. The 
wheat at the latter date looked fairly well, but was attacked in 
places by a small white grub, — the wheat of several farmers 
in the neighbourhood being similarly attacked. The total 
rainfall for February was 2-98 inches, and for the period of sis 
months, 17-95 inches. A week's frost succeeded early in March, 
and left the land in an improved state : only '89 in. of rain fell 
in March, and the land worked splendidly. The wheat, however, • 
looked rather cut down. On April 3rd, it was hoed and pressed 
with the Cambridge roller, and that which had been dibbled in 
to fill gaps in January had now come up well also. On April 13th 
the nitrogenous top-dressings of salts of ammonia and nitrate of 
soda were sown bv a broadcast manure-distributor, after having 
been diluted with about three times their bulk of dry sand. The 
wheat was now cross-hoed. About this time wireworms began 
to appear. Any gaps in the wheat were filled up on April 28th, 
Wireworms again came up at the close of April, and slightly 
attacked all the plots. At the opening of May the plant looked 
healthy, and the ground was fairly clean. Rain, however, 
following, the weeds came up very fast, and were very hard to 
get rid of, the ground not being dry enough to hoe.
