356 Report on the Field and Feeding Experiments at Wohurn. 
The land was ploughed on April 22nd, scuffled on May 9th, 
and ploughed again on May 26th. The dung was applied on 
June 3rd to plots 8, 9, and 10, and the different minerals to 
the other plots on June 3rd and 4th. The seed, 3 lbs. of Gibbs's 
selected purple-top swede per acre, was drilled in on June 4th 
and 5th. The swedes came up well, and singling them was 
begun on June 30th. About this time the fly, however, touched 
them, and rain was much needed, so that the storms of July 
benefited the crop much. On July 21st the land was horse-hoed, 
and again on August 2nd. Nitrate of soda was put on plot 12 
on July 24th. About the middle of August the turnip-grub 
made its appearance, and did great damage to the crop. To 
this cause are due in great measure the differences between the 
duplicate plots. On October 29th the following notes were 
taken : — 
Plot 4a. Big roots, but much scattered. 
Plot 6 (no manure). Fly very marked ; a failure. 
Plot 9a. Roots very necky. 
Plot 8 (farmyard manure). Fair crop. 
Plot 11 A. Seems a pretty good crop. 
Plot 12a. Patches eaten off. 
Plot 12b. Fly in parts. 
The roots were pulled, carted, and weighed between November 
10th and 15th. 
The results are given in Table VI., pp. 354 and 355. 
These results, owing to the damage done to the crop by fly, 
have unfortunately been rendered in great measure not available 
for comparison. A few points are, however, worthy of notice. 
The plots which suffered by far the most were the unmanured 
ones 6a and 6b. The best results on the whole were obtained 
from farmyard manure, the double dose of 20 tons increasing 
the produce 2 tons per acre. The addition of either ground or 
dissolved coprolites to 10 tons of dung increased the pfoduce 
somewhat. As a rule doubling the quantity of manure per acre 
did not tell largely. 
Experiments on Wheat in Lansome Field. 
These experiments on the lighter land of Lansome field with 
different kinds of phosphatic fertilisers were similar to those 
conducted in Warren field. The rotation was : 1881, swedes ; 
1882, barley; 1883, peas; 1884, wheat. The manures given 
in Table VII. were used for the swedes in 1881, the swedes 
being fed off on the land by sheep, with the addition of an equal 
quantity of cake and corn on each plot, at the rate of 4 cwts. 
of barley-meal and 2 cwts. of decorticated cotton-cake per
