Report on the Field and Feeding Experiments at Woburn. 291 
July 10th. The barley looked very well and was a good plant 
all over. On May 27th it was noticed that the nitrogenous 
manures had not as yet shown their influence to any extent, 
nor yet had the dung ; shortly, however, the manures began to 
tell, and, as in the case of the wheat, nitrate of soda, whether 
used alone or with mineral manures, showed itself superior to 
sulphate of ammonia. The heavier dressing of dung also told 
to some extent, though not nearly in as marked a manner as in 
the case of the wheat. A little before harvest it was noticed 
that most of the plots were exceedingly short in the straw, and 
all (especially the heavily manured ones) ripened very badly. 
Harvest was delayed by continuous bad weather, but finally the 
barley was cut and harvested on August 31st — September 7th ; 
threshed and weighed on October 20th-22nd. The results are 
given in Table II. 
As in the case of the wheat, the produce was very low, the 
lowest, indeed, since 1879, The unmanured plots gave only 
19*2 and 18 "2 bushels respectively, as against 21 '8 and 22 "5 
bushels in 1885, itself a year of lower yield than usual. Nitrate 
of soda (275 lbs. to the acre) gave 38 "4 bushels, while ammonia- 
salts (200 lbs. per acre) produced 29*8 bushels. Minerals added 
to the above increased the crop to 40*2 and 32*1 bushels 
respectively ; but mineral manures, used alone, gave no more than 
the unmanured plots. The nitrogenous manures, applied in 
double quantity and with minerals as well, produced the heaviest 
crops, viz., 44 "1 bushels with 400 lbs. ammonia-salts, and 52 
bushels with 550 lbs. nitrate of soda. Farmyard manure, except 
at the higher rate (8 tons per acre), did not have much effect. 
The heaviest yields were, as before, on plots 8 B and 9 B, but 
these were only 44 '1 and 52 bushels, against 58*7 and 64 '5 
bushels in 1885. In the case of the barley, the omission 
for a single season of the nitrogenous manures, though reducing 
the produce enormously, did not bring it so nearly to that of the 
unmanured plots as was the case with the wheat crop. 
The Rotation Experiments. 
It will be borne in mind that, on the conclusion of the second 
4-course rotation in 1885, an alteration of the original plan 
was made, in consequence of decorticated cotton-cake not 
having shown itself superior as a manure to maize-meal simi- 
larly used, with the object of testing if this was due to any over- 
fertility of the land. With a view of exhausting this, if existing, 
the four plots of each rotation were divided by a cross-path into 
8 plots of J-acre each. On four of these plots the rotation is 
continued as before, though the manurial treatment is not so 
heavy or so frequently repeated, while on the other four plots
