48 BRITISH MODES OF CULTIVATING 



linings, and brings them into a growing state, 

 shifting all those not intended for fruiting that sea- 

 son. He covers the frames at night throughout 

 the year with straw, and a sail-cloth over, excepting 

 in the warmest part of summer ; at that season, 

 during fine showers, he removes the sashes en- 

 tirely, and lets the plants receive a gentle watering. 

 He frequently waters over the leaves in the after- 

 noons with a pot having a fine rose, and shuts up 

 early; which he finds produces a moist heat, rapid 

 growth, and keeps down insects. In winter he uses 

 a tin pipe, to keep the water from touching the 

 leaves of the plants ; and as he has a very low tem- 

 perature at that season, he gives them very little. 



Insects. These he is not much troubled with ; but 

 he says, " Such plants as are attacked by them, 

 should be immediately taken out of the frame, and 

 plunged into a moderate hot-bed made of dung ; 

 this hot-bed should be covered with one or two 

 cucumber-frames, adapted to the height of the 

 plants. Let these frames be covered with lights ; 

 so as to confine the steam of the dung. As soon as 

 the plants receive the heat of this bed, water them 

 all over the tops of the leaves with cold water. 

 This will effectually destroy the insects ; after which 

 the plants are to be restored to the covered frame 

 again. A trial or two of this will convince any 

 person of the infallible efficacy of it." P. 38. 



It thus appears that he destroys them by the 

 operation of the ammoniacal gas, much in the same 

 manner as does Mr, Baldwin.
