212 Experiments with Guano, and other Manures. 
N.B. — A bushel of tlie swedes grown on guano weighed, when 
cleaned of top and root, 47 lbs. ; and a bushel of those grown on dung 
43 lbs.* 
The archdeacon remarks very justly, " I am strongly of opinion 
that the guano ought to be mixed with a large quantity of ashes, 
and spread upon the land before raising the rows upon which the 
seed is to be sown." The correctness of this opinion is proved by 
a circumstance communicated to me by Mr. Ridley, of Park-End, 
in this county, last year. He deposited guano in the hollow of the 
rows, covered it up by the plough, and sowed the seed in the 
usual way with a drill, but none of it vegetated ; but after plough- 
ing the land across the rows, so as to mix the guano with the soil, 
ridging it, and sowmg again, he had a very good crop.

* This diflference in weight probably arose from the difference in size of 
the turnips, as small turnips pack closer and weigh heavier than large ones, 
by measure, though less by the acre. It may be observed, too, that in all 
these experiments with farm manure, there is the absence of any test of its 
quality, and the precise state as to the fermentation it had undergone when 
applied to the land, which is sufficient to account for the varying results. 
1 proved by experiment, many years ago, that 1 ton of manure taken from 
a yard in which cattle were fed on fidl turnips, with a portion of oil-cake 
and bean-meal, was worth 3 tons of that (though apparently in equally good 
state) which was made in a yard where young cattle were kept on straw 
during the night, with a run out in the fields, getting a few turnip-tops in 
the day. It is therefore deserving of the farmer's attention, when carting 
his manure, to form heaps in the field for his turnip land, to be careful to 
mix the different kinds intimately together ; or if that should not be con- 
venient, to give to that of poor quality an additional dressing of guano or 
bone-dust. — J. Grey. 
t But for the quantity of ashes with No. 14, I am persuaded there would 
have been no crop at all.— G. Darling,
