weather be suitable to place it out of doors. It will bloom in about 

 ten weeks from the time of sowing the seed. For a window or 

 otherwise, the plants looks and thrives best if the three leads be 

 allowed each a small neat stick to climb up, which at a yard high 

 may form a pyramid, and the plant be stopped when at the top ; 

 pendants will then be thrown out, and flower beautifully. 



If the red spider ever attack a plant, I turn it upside down and 

 immerse it in soap suds for a few minutes this never fails to 

 destroy the insect. 



I have grown both the kinds very freely in the open air, planting 

 them against a wall which has a south-east aspect. I turned them 

 out of pots the last week in April, sheltering them a little with a 

 net till the end of May ; the soil in which they grew was a mixture 

 of peat and rich loam, I had some planted out into my flower 

 beds, which are well sheltered from the prevalent westerly winds, 

 and they too bloomed admirably ; I allowed the plants grown 

 against the walls to twine around upright wires, placed at an inch 

 from the wall, the shoots reached nine feet high last season and 

 bloomed most profusely, and I scarcely need add, produced a very 

 pretty appearance, more especially so when I had a plant of fine 

 blue purple flowered Maurandia Barclayana planted, between the 

 buff and white Thunbergias, the contrast was pleasing : the plants 

 I had in the open flower beds I had trained up acentral wire stem, 

 two feet high, having a head resembling an umbrella of three 

 feet in diameter, the shoots soon covered the surface, and hanging 

 pendant at the extremities were very interesting.

WILLIAMS AND Cos. PATENT WROUGHT IRON BOILER FOR 

 HEATING GREENHOUSES, &c. WITH HOT WATER. 



BY W. GARDENER, KNAP HILL. 



Presuming that all subjects connected with the construction or 

 heating of horticultural buildings will be acceptable to your nu- 

 merous readers, I beg to direct their notice to the accompanying 

 drawing of a boiler invented by Williams & Co., which in my 

 estimation appears to possess merit peculiar to any other boiler 

 used for heating greenhouses and other erections with hot water. 

 The chief feature in the plan is the simple and easy mode adopted
