Report on the Field and Feeding Experiments at Wohurn. 297 
Rotation No. 4. — Four acres. 1886, swedes (2 acres), mangolds 
(2 acres). This was also the first year of the new course of 
rotation, wheat having been the previous crop. The mangolds 
were drilled on plots 5, 6, 7, 8, on May 3rd, no manures at all 
being used ; while the swedes were drilled with 3 cwt. of mineral 
superphosphate per acre on plots 1, 2, 3, 4, on May 19th, 3 lbs. 
of seed being used per acre. 
Both crops came up well, but later on the swedes, owing to fly, 
mildew, and finger-and-toe, were almost entirely spoiled. The 
mangolds, on the contrary, remained strong, healthy, and sound, 
and were a very fair crop. They were pulled on October 29th and 
30th, and weighed ; the swedes were pulled November 8th-12th, 
and weighed on November 16th. The produce of this rotation 
is given in Table VI, (p. 296). 
It is remarkable that without the application of any manure, 
a corn crop having also preceded, so large a produce of mangolds 
as is given in Table VI. should have been realized. A similar 
effect was noted in the case of Rotation No. 2 last year, strength- 
ening the belief as to the excessive fertility possessed by 
the land. 
Experiments on the Comparative Manurial Values of 
Decorticated Cotton-cake and Maize-meal, con- 
ducted IN Lansome Field. 
1885, barley ; 1886, broad clover. Broad clover had been 
sown among the barley of 1885, to which latter crop the different 
manures as given in Table VII had been applied; no further 
manuring was employed for the clover. The plots were 
kept clean and rolled, and the clover was cut the first time on 
June 25th, 1886, made into hay, and carted and weighed on 
June 30th. The aftermath was fed off with sheep and the field 
then ploughed up and sown with wheat. The produce of 
clover hay is given in Table VII. (p. 298). 
With the clover, as with the previous barley crop, the highest 
result was obtained on the plot to which decorticated cotton- 
cake meal had been applied direct. 
Experiments with soluble and finely-ground Phos- 
PHATic Fertilizers in Warren Field (Strong Land). 
Red clover was sown among the barley of 1885. The clover 
was mown the first time on June 26th, 1886, made into hay, and 
carted and weighed June 30th. It was very full of weeds, and 
the previously noticed unsuitability of this field for the con- 
tinuation of experiments being more than ever apparent, it was 
decided to give it up. Accordingly the weights of clover this 
year are not recorded.
