Annual Report for 1887 of the ConsiiUing Chemist. 305 
It is, of course, evident tliat very much depends on the 
proximity of the place of manufacture to the field on which the 
sludge is to be applied ; indeed, this is generally the deciding 
factor. However, the above analyses show that in different 
sludges the composition varies greatly also. No. 1 cost about 
is. 6d. per ton upon the land, and this could not be considered 
too much ; for spreading on grass land it would be serviceable. 
No. 2, costing about the same, would, I was informed, require 
screening as well ; it is decidedly inferior in quality to No. 1 , 
and far too dear. No. 3 is the richest of all, having consider- 
ably more phosphates, and also being higher in ammonia. This 
sludge, I was told, was put on rail free of charge, the cost 
of can-iage to the sender of the sample being ll*. '3d. a ton. 
Though well worth having if near at hand, it would only just 
about cover the cost of carriage. These sewage manures, when 
sufficiently dry, as some of them are, might I think be usefully 
employed for mixing with concentrated artificial manures for 
the purpose of diluting them and procuring better distribution. 
Ba^c Cinder. — I was in hopes of being able to report 
the results of some experiments on swedes which I have con- 
ducted with this material, upon two difierent fields at Woburn, 
especially as considerable public attention has been directed to 
basic cinder, which, if found to be of pi-actical value, must 
prove a valuable addition to our supply of phosphatic manures. 
Unfortunately, however, owing to the extreme drought, the 
results, so far as the basic cinder is concerned, are not satis- 
factory ; but so much is due to the untoward weather that it 
would be unfair to draw any conclusion as to the efficacy of the 
manure. 
I have contributed the following Papers to the ' Journal ' of 
the Society during the year : — 
1. Report on the Field and Feeding Experiments at Woburn 
during the year 1886. 
2. Report of Experiments on Ensilage at Woburn, 1886-87. 
3. Sheep-Feeding Experiments at Woburn during 1886-87. 
4. Report on the Experiments conducted in 1886 by Local 
Agricultural Societies in conjunction with the Royal Agricul- 
tural Society of England.
