attention, and would prove to agriculturists a most interesting 
study. In all the experiments he had been eminently successful, 
and the committee, with much confidence, award him the first 
premium. 
Dr. Manson, as the only other competitor, the committee con- 
sider entitled to the second premium. His experiments show 
that good turnips may be raised by two cwt. of guano, bones, 
and sulphuric acid, at an expense of 11. per acre; but are not 
sufficiently calculated to test the values of the different manures 
used. 
The committee refer the Club to the reports of both these 
gentlemen as to the mode of conducting, and the result of their 
experiments, and which will be found to give them explicitly and 
fully. 
The committee cannot conclude this report without commend- 
ing Mr. M'William's enterprise and perseverance in the highest 
manner. The great apparent care and trouble taken by him in 
conducting and bringing to a successful issue these numerous 
trials, are deserving of the highest praise, not only as being con- 
ducive to the interests of agriculture, but to the community at 
large. His experiments are all simple, and easy to be under- 
stood ; and when his report of the minute different results is 
before the Club, the committee have no doubt but they will 
derive much practical benefit from it. They recommend that the 
report should be printed, and a copy sent to every member, along 
with his description of a cart, constructed by himself, of simple 
mechanism and small expense, for the application of the bones 
and acid when diluted.

Experiments made on Turnips with five different hinds of Manure, 
on the Farm of Gordon Castle, in the year 1 843. 
The seed (Dale's yellow Hybrid) was sown on the 15th of June; 
and, as it was wished to ascertain the result while the Duke was at the 
Castle, the Turnips, before they came to maturity, were taken up on 
the 3rd of November, and carefully topped and weighed. 
1st, One Imperial acre manured with 8 bushels of bones and 14 
cubic yards of farm-yard dung, at an expense of 3/., produced 12 tons. 
2nd, One ditto, manured with 2 cwt. 91 lbs. of guano, at an expense 
of 1/. I7s. 4rf., produced 11 tons 4 cwt. 
3rd, One ditto, manured with 16 bushels of bones, at an expense of 
1/. IG^., produced 11 tons. 
4th, One ditto, manured with 83 lbs. of sulphuric acid and 2 bushels
