a portion of which had been grown under Mr. Pilkington's bell- 

 glasses, whicli differ from the French cloche in having a ventilator 

 at the top, in the shape of a neck or chimne}', which can be left 

 open or kept close as may be desired, by covering it over or not 

 with another small bell-glass, made for the purpose. In this 

 way, damp from the soil, which is often so destructive to winter 

 Lettuces, can be let off without tilting up the side or moving the 

 bell-glass in any way, as has to be done in the case of cloches 

 whenever air is given. The result of this trial has been very 

 satisfactory — for, of a ridge of Lettuces planted out last October, 

 those which had bell-glasses put over them on the 27th of last 

 month have attained nearly double the size of such as were left 

 unprotected ; but which, in all other respects, were treated pre- 

 cisely like them. It was mentioned, however, that bell-glasses 

 can, unfortunately, only be had in the neighbourhood of places 

 where they are made ; for, owing to the difficulty of packing 

 them in small compass, the packing and carriage cost more than 

 the original value of the glasses themselves.
