acter may attach to each of the protectors, or accelerators, which 
we have suggested. In tlius proceeding, we do not wish it to be 
understood that we are rash enough to advise parties to do away 
with the frames or pits which they already possess, and to forth- 
with adopt, at a considerable sacrifice, the forms of structure we 
have recommended. This is assuredly not our aim ; those who 
possess an establishment already, considered tolerably complete, 
will do well to abide by it; for it is not, after all, merely this 
or that form of structure, but good principles of culture, 
attentively carried out, which ensures success in the main. 
To accomplish all this it is necessary that the cultivator 
thoroughly understand first principles; these must be kept 
distinctly in the mind’s eye — once thoroughly established and 
confirmed, every point of mere practice must be subjected to 
their strict analysis. We think, therefore, that we cannot better 
discharge our duty, than by adverting to, and explaining, those 
principles of culture ; simplifying them as much as possible. 
In doing this, we must, as a preliminary step, turn back to page 
100 of the Auctarium, at which is given an ennumeration of 
some useful matters; the forcing, culture, or conservation, of 
which may be carried out, in the most perfect way, by the sys- 
tem of protectors or accelerators here proposed. 
We must now, in recapitulating the objects named at pages 
100 and 101, take the liberty of transposing the order of them 
as they there stand ; they were thrown down as they occurred 
to the mind, as fitting objects; we must now, however, endea- 
vour to arrange them according to their habits; and this, we 
trust, will at once prove a guide both to the amateur, and those 
who are merely in the beginning of horticulture. 
Classification of the Objects.
