This plan of sowing seeds, or of planting young plants intended for transplantation, into pots made of turf, is not only applicable to cucumbers, but might be very extensively adopted in the case of annuals and half hardy plants raised in frames, during the spring, in large quantities for the flower garden. In these cases, however, as the quantity that could be reared within a given space would be an object, the turves should be as small as possible in their lateral dimensions--a bore of two inches and a half, with half an inch on each side, thus making the diameter three inches and a half, would be found convenient in this respect. For cucumbers, however, or when the plan was applied to any special object, a larger size might be employed, which would allow of the plants attaining a larger size before it would be necessary to place them in their permanent positions. _On Watering the Soil._ In the diagram at p. 18, and the description of it at p. 20, I have indicated and recommended a plan of moistening the soil by pouring water down beneath the soil: this was to be done by the help of tubes provided for the purpose. The soil was supposed to rest on the top of the hot water-tank, which was to supply bottom heat; and immediately beneath the soil, a layer of open rubble was proposed to be placed, among which the water applied might find its way, and gradually moisten the superincumbent soil. Mr. Hunter, gardener at Mawley Hall, in detailing[3] his sixteen years' experience in tank-heating, has in great measure corroborated these views; and as his corroboration of the plan I have recommended, embodies some useful hints, I will quote the substance of his remarks:--"I had a pit erected, thirty-eight feet long, seven and a half wide, divided into four compartments, for growing melons and cucumbers, with a tank extending the whole length of the pit, six feet wide and six inches deep. Across this I put larch spars, and upon them turves, with the grassy side downwards, and on them the soil for the melons and cucumbers. The plants grew and did well for a time, but they were of short duration in comparison with the dung-bed. Instead of the moisture ascending through the soil as I expected, I found that the heat from the tank dried the turves and soil next to them as dry as dust, and that there was no such thing as obtaining a moist heat from hot water without the soil was in contact with it. Next year I put broken stones upon the spars, and turves upon them, and made my arrangements so that I could occasionally run water in the tank to wet the turves and the soil next them. This was an improvement; and I went on prosperously for some years, till the spars began to decay. I then had iron bars put across, and two of the compartments covered with squares, a foot in diameter, and one inch thick; the other two with slates; both slates and squares jointed with Roman cement, to prevent the soil from getting into the tank, as I had found the
