XI. — Besults of the Experiments carried out on Manor Farm, 
near Rochester, by the Rochester Farmers' Club, to ascertain the 
relative Value of Soluble and Insoluble Phosphates. 
The 10 plots upon which the manures were applied had 
manures of the same money value in each case. It will be 
observed that the weight varied greatly ; for instance, 53 lbs. 
of finely-crushed bones cost the same as 112 lbs. of raw 
coprolites, &c. 
The turnips (Purple-top Swedes) were sown June 21st, and 
pulled up and weighed November 11th and 12th. The tops 
were not removed ; the fibres and soil only were taken from the 
turnips.

A crop of barley taken from the land in 1879 was preceded 
by a crop of Green Round Turnips, upon which sheep were 
* Purple-top Swedes. 
■f In comparing the results of these experiments with those given on the pre- 
ceding pages, it must be bnrne in mind that in this case the to2Js were weighed as 
■well as tlie roots, but that in the other experiments the weights of the roots only 
are given. — Ed.
