 berries may be 

 forced, growing 

 either in pots or in 

 the borders of the 

 house. They may 

 be also planted on the outside of a pit, 

 the bearing canes being introduced 

 withinside and trained to a trellis, 

 whilst the present year's shoots are left 

 outside.

RENDLE'S TANK SYSTEM of heating 

 was first suggested, we believe, by Mr. 

 Rendle, nurseryman, of Plymouth. A 

 tank of iron or wood, twenty feet long, 

 five feet broad, and six inches deep, is 

 constructed in the centre of the house, 

 and surrounded by a walk, except at 

 the end, where the boiler is fixed for 

 heating it. The top of tbe t tank is co- 

 vered with large slabs of slate, cemented 

 together, to prevent the excessive es- 

 cape of steam. Around this is a frame 

 sufficiently high to retain the bark, in 

 which the pots are plunged. The boiler 

 and tank are filled with water, and this 

 circulates, when the fire is lighted un- 

 der the former, by means of two pipes, 

 one from the top of the boiler, and the 

 other returning nearer to its bottom. 

 The expense of pipes, and the danger of 

 their freezing, is avoided; the fire only
