faction to observe, that very nearly the whole of the compost ad- 
hered firmly to their roots ; and that their growth, subsequently, 
was not apparently checked in any degree, by their transplant- 
ation. They were placed in rows, contiguous to those which 
had been previously sown; a small quantity of compost, similar 
to that put into the pots being added ; and the common mould 
was then closed round their roots, and raised upon each side of 
the rows. Sticks to support and protect the plants were imme- 
diate! y added in rather more than the ordinary number and quan- 
tity ; and .subsequently, no particular care or attention was paid 
to them. On the morning of the 29th of April, I ascertained 
the comparative growth of my plants, which had been subjected 
to the different modes of treatment above mentioned, in two 
rows which grew contiguous to each other: A\hen I found the 
height of those which hadbeen raised in pots to be fifteen inches; 
and that of the others to be scarcely four inches; and I much 
doubt, whether I ever possessed in the most favourable season, 
as forward a crop of peas as my garden now contains. 
Many causes appear to me to have operated in conjunction, 
to produce the foregoing effects. It has long been known that 
snow does not, in winter, lie so long upon the ground which has 
been manured in the same season, with fresh unfermented stable 
manure, as upon unmanured ground; and therefore I conclude, 
that some degree of heat existed in and emanated from the com- 
post; though probably, never in a sufficient degree to have been 
sensible to the touch of any warm-blooded animal. If placed in 
a considerable heap, such a compost as that described, and even 
when the stable manure is much less in quantity will heat violent! y. 
I have often suffered the compost of this kind, which I employ 
for pine-apples, to become hot, to prevent the subsequent ap- 
pearance of earth-worms in it. If heat was in any degree gen- 
erated by the compost in which the peas grew, the escape of it 
was necessarily retarded by the numerous sticks by which the 
ground was partially covered; and liftle injury could have been 
sustained from the shade of those, because the quantity of light, 
comparatively with the temperature of the air, and growth of 
the plants is very great after the vernal equinox; and it is every 
day increasing in power and influence. Another cause of the 
rapid growth of the transplanted peas, has probably, been the 
very favourable state of the soil, in which they have been placed
