es THE FORCING GARDEN. 
the thermometer, above the outside temperature, for a 
fortnight. Keep the sashes close. In the course of a 
fortnight the thermometer may rise to 60° and then to 
65°, at which it may stand, with a rise of 10° during 
sunny days. Keep the sashes closed, water with tepid 
water, and sow some salt over the bed once or twice. 
This will wash in, and help the Asparagus. It will be 
necessary to treat the beds in the usual way before 
commencing to force, viz. fork the surface over, and 
then rake it off fine, so that the heads may come 
through freely. It is necessary to stop cutting before 
the plants get exhausted; the cutting must not there- 
fore be continued too long, and the heat may be dis 
continued as soon as it is done, air being then admitted. 
lt will be advisable in frosty weather to cover the 
sashes with mats. If the roots are not driven beyond 
their strength, the bed will last many years. 
A small elliptic boiler of twenty-four inches will 
heat a pit of one hundred feet long, costing 2l. 3s. 
The two hundred feet of three-inch pipe will cost 
71. 10s. carriage and all; four elbows, at 2s. 8d. each, 
10s. 8d. The fixing of the boiler, bricks, &c. will cost 
2l.; the india-rubber rings for fitting the pipes, 5s. per 
pound. Here then is a good, simple, and effective 
apparatus for sufficiently heating such a pit for a 
little more than 101. The cost of the pit, sashes, &c. 
may be compared to the Melon pit, frames, &ce. 
SEA-KALE. 
Many methods are adopted to get early Sea-kale, 
but I know of none to equal covering up the roots 
where they stand. Sea-kale will not bear a great dry
