greenhouse is crammed, the plants drawn, whilst one or two 
merely of our protectors, which we will shortly describe, would 
so far relieve the houses of their superfluities, as to ensure well- 
grown stock. 
We must here observe that the suggestions we make, relate 
principally to small gardens ; they will, nevertheless, in the 
main, be applicable, as a subordinate branch of a system of 
forcing and plant structures, in the most extensive establish- 
ments. 
We have five forms of protective or accelerative structures 
to offer, which we consider to be all that is requisite: two of 
them are already pretty well known ; for the other three, we 
must coin titles, in order to distinguish them. 
1st, Portable opaque protectors. 
2nd, Portable glass protectors or accelerators. 
3rd, Portable drill covers. . 
4th, Portable sashes. 
5th, Hand glasses. 
We may just premise, that for the first two structures we 
intend to propose some light brick pits, which will, in divisions, 
receive at any time, any of the opaque or glass protectors, which 
may happen to be at liberty ; — our prime object being, Lliat 
not a day shall be lost, but that they be constantly employed. 
They will all be so very light, that a lady amateur, assisted by 
her maid, may, at any time, remove one of them without fur- 
ther assistance. This we consider a most important affair, for 
the old three-light frames are so cumbrous as to preclude any 
attempt to move them about by lady gardeners.
