Indeed, some of our market gardeners who have never grown a mushroom or seen one grown, but who know well that some of their neighbors are making money out of this business, instinctiv

You can have shelves above it for domestic purposes, just as you would in any other part of the cellar.

When the lid is shut they are secure from cold and vermin. Thus protected the cellars can be ventilated without interfering with the welfare

Having been well sweetened by previous preparation, it is now cool and free from steam, and almost odorless; after a few days it will warm up a little, and may then be spawned and earthed over at once.

However, I was pleased to see all the floor of the room not occupied by the boiler covered with little flat mushroom beds and bearing a very good crop. Truth to tell, I used to fear growing mush

And this pays; and if it will pay a man to get manure at such a cost for mushroom-growing, how much more will mushroom-growing pay the farmer who has the cellar and the manure as well? Mr. Gardner raises mushrooms,

The bed was fifteen inches thick. In making it the manure was first shaken up loosely to admit of its being more evenly spread than if pitched out in heavy forkfuls, and it was then tramped down firmly with the feet. The bed was then marked off into halves. On one half (No. 1) a layer of a little over three inches of loam was at once placed over the manure; on the other half (No. 2) no loam was used at this time, but the manure on the surface of the bed-about three inch

The cellars are seven and one-half feet high inside; the beds five feet wide, nine inches deep, two feet apart, and run parallel to one another the whole length of the cellar. The beds are three deep, that is, one bed is made upon the floor,

The loam is the ordinary field soil from his market garden. He tells me he has better success with beds made up in this way than when manure alone is used. We all know how very heavily market gardeners manure their land, also how vigorously most writers on mushroom culture denounce the use of manure-fatted loam in mushroom beds, but here is Mr. Den

This tunnel or arch is seven feet high in the middle and eight feet wide within, but a raised two-feet-wide pathway along the middle lessens the height to six and one-half feet. Between this pathway and the sides of the building there is only an earthen floor, but it is quite dry, as th

The cross-bars rest in sockets in the wall made by cutting out half a brick every four feet along the wall, and on upright strips or feet one and one-fourth by four inches wide, or two by three inches, set under the inside ends of the cross-bars and resting on the cement floor close up against the lower bed. By having this foot end a quarter of an inch higher than the wall end the heavy weight of the bed is thrown toward the wall. Loose hemlock boards set close together form the flooring, for there is no need of n

A close door at either end of the mushroom cellar proper separates it from the end pits. The cellar is divided in the middle by a partition. This gives, when it is in full working order, eight beds, each thirty-one and one-half feet long, or a continuous run of 252 feet or 756 square feet of surface, and as the beds are renewed twice a year this gives 504 running feet of bed, or 1512 square feet of surface. A common average crop is three-

The hot water passes from the boiler to an open iron tank placed two feet above it, as shown in the engraving, and thence down through a perpendicular pipe till it reaches and enters the horizontal pipes that pass around the cellar and, returning, enters the boiler again near its base. The boiler and pipes are filled from this tank, which should always be kept at least half full of water, and looked into every day when in use, so that when the water gets lower than half full it may be filled up again. About 134 running feet of four-inch pipe are included inside the cellar (sixty-four feet on each side and six feet across at further end); this give
