bles may be steam-boiled at once, as every pitcher may con-tain a separate kind, and, from their commodious size, theycan be easily moved where wanted*. See Plates XI and XII.
All steam boilers, with screwed covers, should be so con-structed as to supply themselves with water. This may bedone by means of a cock balanced to a float within the boiler,which falls and rises with the surface, and of course opens orshuts the cock through which water is admitted into the boil-er, in the same manner as in steam engines. They should havea safety valve, to prevent accidents.
J 2. Cart-shed and Repository for Implements.
The cart-shed is commonly so placed that the access to itmay be easy and open from the road, and in most cases it willbe found tp suit best when placed under the granary, wherethe same roof covers both. The open space for the carts andploughs admits a free circulation of air under the granaryfloor, and thus keeps it free from damp ; and the carts canbe loaded from the granary, when wanted, with the greatestease, by means of a hatch. Such sheds need not be above sixfeet high, and the distance between the pillnrs not more thanseven or eight.
13. Root-house.
On all farms where cattle are kept, a store-room is appro-priated near the feeding-houses for containing turnips, pota-toes, &c. The method of covering up potatoes in the field ha-ving been found to answer, no more space will be wanted forthem, than what is sufficient to contain one of the field pilesat a time. It is found convenient to have the root-house ofdimensions sufficient to admit of a cart being turned up, andemptied within it.
