ing stopcocks to the tray, no steaju will arise ; or, by having a 

 cover to it, this can be effected. Should you require it for 

 cucumbers, &c., you can have as much moist heat as you de- 

 sire. Should the v^^eather change to either more heat or cold, 

 by allowing or not allowing the water its free course, you can 

 command it. The roots of your pines cannot be burnt, and 

 by properly managing the apparatus, your bottom heat may 

 be what you please; and indeed by having stopcocks at each 

 branch, you may cut off the bottom heat altogether, and yet 

 have sufficient warmth from the mains at the bottom of the 

 bed. My boiler would, I am convinced, heat six such beds, 

 of course having mains and laterals sufficient for each bed, so 

 little fire being necessary, and requiring but little attention, 

 when once the water is hot. I closed the frame the other 

 night at about 1 2 o'clock, at 73"^, I also shut the furnace damper ; 

 at 9 in the morning the heat in the frame was 72°, the fire 

 was then out, and at 12 o'clock noon I tried the water in the 

 boiler, and found it to be 118°, quite sufficient for every thing, 

 although neglected for twelve hours. My purpose is to con- 

 tinue my experiments, and try a few pines, as I really think I 

 shall be able to do more and much sooner by these means than 

 the usual methods of tan and smoke flues. I shall be happy 

 to receive hints from any of your valuable correspondents on 

 the subject, and should a more perfect explanation be required 

 by any brother amateur, it will afford me much pleasure in 

 assisting him. I am. Sir, &c.

Art. VII. On a Winter Garden. By T. R. Rivere, Esq. 



Spring, the most delightful season of the year, wants no 

 panegyric; it is felt, acknowledged, and enjoyed by all: even 

 the heaths, moors, and forests present us with various tints 

 and hues : indeed, the whole country blooms, and is a kind of 

 garden, and affords more various beauties than are to be found 

 even in a garden at another season. But art can do what 

 nature, uncultivated, forbids ; for in the most uncomfortable
