The greenhouse heating equipment advertised in this paper is, we believe, the best for the trade to buy, and each article the best in the special field of its adaptation. PIPING FOB HOTB^S. >^ I am enclosing a diagram of some hotbeds and should like to know whether the system of piping there shown would be suitable for the grow- ing of lettuce, beets and radishes, in this New York climate. Which would be the better place for the pipes—about five inches underground or above the surface, about one foot from the back and front! The piping will be con- nected to the boiler with shut-off valves, so as to maintain a tempera- ture of 45 to 50 degrees. It is impos- sible to buy manure here for the mak- ing of hotbeds. F. M. V. N. The sketch shows two hotbeds, each 6x60 feet, with a 2%-inch flow pipe running up one side and back on the other. This should be sufficient to maintain a temperature of 50 degrees in zero weather, if placed above ground. By running the pipes underground, eo that they would be covered with six inches of soil, bottom heat would be furnished, which would materially pro- mote the growth of the crops men^ tioned, and especially of lettuce. Thar radiation in this case would be suffi- cient after the first part of March, but in extremely cold weather the frost might work in around the sides of the bods unless some form of covering is u?ed.
