II. at the north end of the greenhouse, into which there is a door (;•) from the porch. Over this glass door a head-light of one pane (s) swings upon pivots, and lets the warm air into the grcenlionse. Under the tlircsliold of this door is a cast iron grating, (<) com- municating with an air drain under the floor of tlie house. This drain has a regular fall of several inches: thus a ciiculatiun of warm air is kept up on the Polmaise principle. ^'ory little fuel is consumed : less than a bushel of coke in :21 hours, at a cost of about id. It rcijuircs [ very little attention ; when the fuel-pipe is filled to the top with coke, and the lid put on, the contents of the pipe b will last from ii to :i4: hours without re- plenishing: according to the heat required, and the draught given by means of the damper and ventilator. The iiue is a four-ineh iron pipe, with a nicelj'-made damper fitted into it. There is a double door to the furnace and ash-pit. In the outer door is a circular brass ventilator or regulator. The short iron liipe- flue mttst pass into a brick chimneij—thin is indis- pensable. By means of the damper and ventilator, the nicest possible regulation of draught may be mahitained. The atmosphere of the house is never quiescent: an undulation of the vine-leaves is always perceptible. I have now tried it for two years; it has never failed to do all that I wish. The flre never goes out, night or day (if the coke is broken small e
