MISCELLANEOUS COMMUNICATIONS AND NOTICES, 
I. — Experiment on Manures. By Sir William Heathcote, 
Bart., M.P. 
Sir William, 
Below I send you an account of the experiment made on the 
■wheat crop at your Home Farm in the course of last year, with different 
kinds of manure ; with my remarks during the growth of the crop, and 
my opinion on the final result of the trial. 
Your directions, given to me in writing, were as follow : — To manure

with 3 cwt. 37 lbs. of artificial Guano (Potter's). 
The field chosen for the experiment contains 37 acres nearly, and does 
not vary much as to quality. It has a gentle inclination to the south, 
and was in all respects in such a state of cultivation as to give an equal 
chance to each parcel : it was a clover ley, and had been mown twice 
during the summer, yielding at the least 3 tons of hay to the acre, and, 
when ploughed, above half a ton more per acre was buried. 
The allotments having been carefully measured off, and plugs driven 
firmly in to mark their bounds, the dung-carting, ploughing, and press- 
ing being completed, the artificial manures evenly sown, and the whole 
sufficiently harrowed, 3 bushels of wheat per acre were drilled on the 
27th of October and the following day. 
The sowing of the manures on the press, and before the harrow, was to 
secure the wheat from injury by coming too closely in contact with 
them. 
Observations during the progress of the Crop. — The wheat came 
away evenly, except in a verv few spots where Daniel's manure had 
touched the seed, and these looked sickly during the winter and spring; 
and, indeed, where Daniel's manure was the only dressing, the crop 
never looked better than No. 7, which had no manure, if so well. The
