286 Report on the Field and Feeding Experiments at Wohum. 
but all through plot 10 B the plant was thin. Wireworms had* 
further made some ravages, especially on plots 1, 2, and 3. 
Top-dressings of ammonia-salts and nitrate of soda were sown, 
on plots 2, 3, 5, 6, 8 B, 9 B, on April 22nd, in the usual way, 
viz., by a broadcast manure distributor, after being mixed with- 
three times their quantity of dry sand. The plots were then 
pressed with a Cambridge roller and harrowed. Any gaps left 
were filled in during this month. Hoeing was commenced 
towards the end of April. On May 8th an inspection of the 
plots showed that 8 B and 9 B looked decidedly the best of all, 
5 and 6 being next in order. Of these the nitrate of soda plots 
looked rather the better. Nos. 1, 2, and 3 were very backward,, 
while No. 4 (minerals only) seemed better than the unmanured 
plots. There was at this period no difference to speak of 
between the plots which had received the heavy and the light 
dressings of dung respectively. Of the duplicate unmanured 
plots. No. 1 was poorer than No. 7, and the plant was thinner 
on it. On May 27th, plot 1 (unmanured) was decidedly the 
poorest, and inferior to the duplicate (unmanured) No. 7. 
A great deal of rain had fallen about this time and the ground 
was in a very wet state. The nitrate of soda plots, 6 and 9 B,. 
had by this time gone considerably ahead of the corresponding: 
ones manured with ammonia-salts ; in each case the more 
heavily-manured plots had the advantage ; the influence of the 
heavier dressing of dung on 11 B had also begun to tell. Plot 4 
(minerals only) was much the same as the unmanured plot 
No. 7. Plot 2 (ammonia-salts alone) was still very thin, and 
No. 3 (nitrate of soda alone) was decidedly better. 
At the beginning of July the relative positions were very 
similar, the nitrate of soda plots showing a marked ascendency. 
Plot 6, though perhaps not the heaviest, looked on the whole 
the best plot on the field. Where nitrate of soda and ammonia- 
salts were omitted (8 A, 9 a) for the single year, the appearance 
of the crops was not better than on No. 7 (unmanured). The 
withholding of the dung in the case of 10 A and 11 A made tLem. 
hardly better than 7 (unmanured), but the small quantity of 
dung (4 tons) also showed very little resulting benefit. 
The harvest was considerably delayed by continued wet 
weather in August, but plots 7 and 11a were cut on August 25th, 
and the remaining plots on August 31st, all being carted and 
stacked in the field on September 1st. 
The wheat was threshed in the field, October 20th ; the straw 
was weighed at once, and the corn a few days later. The 
results are given in Table I. 
The produce, doubtless owing in great measure to the un- 
favourable winter and the prevalence of early frosts, has been
