squares, or along the sides of a parallelogram or polygon, and either 
detached from, or connected with, the horticultural buildings. 
The manner in which the working-sheds are heated by the waste heat 
from the furnaces, in consequence of which, in severe weather, much 
more work will be done in them, and in a better manner, and in which 
they are lighted, so as to serve for protecting certain kinds of plants 
during winter, is worthy of imitation ; as is the mode of heating so 
many different houses from only three boilers. In no garden structures 
have we seen a more judicious use of the Penryhn slate ; paths, edgings, 
shelves, cisterns, boxes for plants, copings, kerbs, partitions, and sub- 
stitutes for dwarf walls, being all made of it. The order and neatness 
with which all the different tools, utensils, &c., are kept in the horticul- 
tural and farm buildings, are most exemplary, and greatly facilitate the 
despatch of business. 
In the farm buildings, the fittings up of the poultry-houses, the rabbit- 
house, and the dairy and dairy scullery, well deserve attention ; and also 
the arrangement for fermenting the food of the pigs in under-ground cis- 
terns, not too warm for summer, nor so cold as to check fermentation in 
winter. The manure of the horses, of the cows, of the pigs, of the rabbits } 
of the pigeons, and of the poultry, is kept in separate pits, that it may 
be used, if desirable, in making up different composts. 
There are three liquid-manure tanks, in which the liquid matter, which 
in most farmyards is wasted, is fermented, and afterwards mixed up with 
soil for use in the kitchen-garden, or used in forming composts for particu- 
lar plants. The liquid-manure from the stables is kept apart from that 
from the cow-house ; and the general drainings of the yard, and of the 
frame-ground in the kitchen-garden, are fermented by themselves. The 
liquid manure with which Mr. Pratt waters his plants is formed chiefly of 
the sweepings of the pigeon, rabbit, and cow houses, with lime ; and is 
kept in a cask in a close shed, (60 in the plan Fig. 6, in p. 46*2, 463,) so 
that the temperature admits of its fermenting in winter, as well as in 
summer : a thick scum rises to the top of the cask, and the liquid is drawn 
out from the bottom as clear as old ale. The plants which Mr. Pratt wa- 
ters with this liquid are chiefly those of rapid growth, such as the Datura , 
Brugmansizz, and other soft-wooded tree plants which, like these, are cut 
in every year, and appear to profit by the stimulating effect of this manure. 
He gives it also, occasionally, to various other plants which appear to
