TTIH PLEASURE GROUND. 263 



hot water apparatus, not merely for horticultural 

 purposes, but for conducting that clement into more 

 extensive buildings, where its application has been 

 found to give very general satisfaction. 



The plan and section, represented in this Plate, 

 Fig. 2, is a Pinery,, heated with one boiler, by Bar- 

 well and Co., who have introduced very simple 

 and effectual valve cisterns b b, whereby the water 

 can be turned off at either, or both divisions at 

 pleasure. The boiler «, is placed in a niche in the 

 back-wall, a pipe proceeds from it to the valve cis- 

 terns /; b, which communicate with the pipes c c, 

 that convey the water to the reservoirs d d } at the 

 extremities of the house. Messrs. Barwell and 

 Co. have introduced these valve cisterns in the heat- 

 ing of several forcing-houses for Lord Melbourne, 

 and other Noblemen, as well as in the range of hot- 

 houses in the Garden of R. Trevor, Esq. of Tingrith, 

 Bedfordshire, who is devotedly attached to horti- 

 cultural pursuits and rural improvements,* having 

 lately formed an extensive sheet of water, whose 

 margins are richly ornamented with hardy flowering 

 shrubs, &c. 



* The Author cannot let slip this opportunity of noticing the 

 admirable neatness in which the Gardens at Tingrith are kept ; 

 they do infinite credit to the industry and attention of the gar- 

 dener, Mr. Phillips. One of the finest horticultural sights I ever 

 saw, was the flowering here of that noble plant, the Bignonia 

 venusta, which is trained along the back of the Pine Stove; and, 

 in November last, was brilliant, with an absolutely inconceivable 

 multitude of blossoms.
