There are undoubtedly many who would enjoy having a small greenhouse, but are prevented on account of the expense, the main item of which consists in a suitable apparatus for heating; and as six years of uninterrupted success with my own greenhouse, at a merely nominal outlay, has demonstrated that it is within the reach of the many, I give you the result of my plans and experience.

This confidence in the solution of the problem is confirmed, not only by my own good fortune, but by the experience of others, who, adopting this plan, have met with as unqualified success as myself, therefore it cannot be considered an experiment.

The building is 11 feet by 25 feet, outside measurement. I put in a foundation 3 feet deep, 12 inches wide, on which the sills, 8x8, are laid in liquid cement; upon the sills are placed 2x4 studding 16 inches apart, 11 feet high in the rear and 3 feet high in front.

Matched sheathing is put on the studding outside and inside, leaving an air chamber of 4 inches all around the building. Over the outside sheathing is placed tarred building paper, and over this the siding.

Seven rafters of 3x6 dressed hard pine are placed equi-distant from the plate on the back to the front, with stops running the whole length for the upper and lower sash, (Fig. 1), making eight spaces for sash which are set with three rows of double-thick glass, bedded in white lead, and with a very narrow lap - not to exceed 1/4 of an inch - to prevent breakage by frost.

The greenhouse faces south and in the east end Is the entrance door, swinging in and back, with a storm porch and door outside [s. p. Fig. 2).

A bench (f)3 1/2 feet wide runs the entire length on the front, and the same width on the rear (b) from the edge of the heating pit (p) to the east end of the house, being slanted to allow the door to swing back (Fig. 2).

The bottoms of the benches are made of common boards, with a 6 inch dressed piece nailed on the edge, making the benches about 5 inches deep, filled two thirds full of clean sand in which the pots are bedded.

The floor of the walk, (w) 3 feet wide, between the benches, is made of 2-inch strips laid about 1 inch apart and nailed to cross pieces (Fig. 1), allowing dirt and water to fall between.

Athough the heating arrangement - the cost of which prevents many from having greenhouses - may have been used before, I have never seen it spoken of or suggested in any article on the subject, and I assume the credit of the plan until advised to the contrary.

It is as follows: In the northwest corner of. the house I dug a pit 4 feet 10 inches by 6 feet, 3 feet deep, laid up in cement with an 8-inch brick wall level with the floor, the bottom being thoroughly grouted to prevent water seeping in from the outside in the spring and fall.

In this I placed a first-class hard coal base-burner stove (s) (I use a Garland No. 30, but any first-class stove will answer) and connected an 8 inch square galvanized iron pipe (fl) to the collar of the stove, the pipe running on an incline upwards to the chimney (c) and under the back bench (Figs. 2 and 3). The chimney has an 8-inch straight flue and extends about 5 feet above the building.

All with whom I talked at the outset feared there would be trouble with gas leaking from the stove or pipe, but in no kind of weather have I ever been able to detect the slightest trace of gas, and in healthfulness the plants uniformly cannot be surpassed.

The stove consumes about three tons of coal during the winter (from the last of October to the last of April), and there has never been the slightest difficulty in keeping up sufficient heat. With the thermometer frequently indicating as low as -25° to -30 I have never had a plant chill, and the temperature generally ranges from 50 to 6o° on the coldest mornings. In extreme weather I have regulated the stove not later than 11 p. m. and, as showing its reliability, I recently fixed the fire at 10.30 p. m., and in the morning at 6.30 the thermometer indicated 570 inside, while it registered -300 outside. As an additional protection, light wooden shutters are placed over the lower sash at night during cold weather.

The size of the pit is immaterial, provided it be wide enough to accommodate the stove and long enough to allow a person to open the front doors and remove the ash pan. The advantage of bricking up the pit consists in the fact that the whole surface becomes thoroughly heated and radiates its heat when the stove cools off towards morning - independent of the necessity of keep-ing out water.

By having the pipe run under the back bench, I get sufficient bottom there for starting cuttings of all kinds, and on the bench keep callas, tea roses, salvias, amaryllis, and plants that require considerable heat, and by placing a triangular bench over the pit (Fig. 1) I have been enabled to successfully keep some varieties of stove plants. On the front bench I keep primroses, carnations, cyclamens, arbutilons, geraniums and plants that thrive well with less heat. The space around the pit also affords an excellent place for starting seeds. Brackets and shelves on the rear wall furnish a place where cactuses luxuriate.

The galvanized iron pipe will have to be renewed once in four or five years, but aside from painting, coal and an occasional pane of glass, there is but little, if any, expense.

The contract price of the greenhouse was $180, exclusive of stove and brick-work, which brought the entire original expense to about $260.

Pots and soil are kept under the front bench. The house will hold from 600 to 1000 plants according to size. I generally have from 700 to 800. This number can be taken care of as a pleasure and recreation; more might become a burden.

The stove would heat a house at least ten feet longer, and the idea has been suggested of building a span roof, altering the inside arrangement to correspond, having a centre bench and two narrower side benches. This plan might be followed when it is desired to plant roses, etc., on the centre bench, and have a more pretentious greenhouse.

I feel confident that any lover of flowers can indulge his tastes inexpensively with this kind of a house, and it can easily be made to pay running expenses by the sale of flowers and plants if desired.

The engraving (Fig. 1) shows a view of about three-fourths of the interior and was taken the middle of last February.
