(Continued from Vol. VII. p. 649.) GARDENING, as we have before observed, is not so much to be improved from within itself, or by the experience of its practitioners in their own departments, as by calling in, and bringing to bear upon it, other sciences and arts. There are some of our readers, no doubt, who would be much better pleased to see our pages confined to short practical papers on the culture of the different articles grown in kitchen and flower gardens, than to read discussions on subjects of general improvement contained in such articles as those of which the present is a continuation, or to study the accounts of inventions occasionally brought forward in our General Notices, (p. 12.) We consider persons entertaining this opinion as taking too confined a view of our duties; because we know that almost all the improvements of any consequence which have been made in gardening have been drawn from other arts and sciences. What improvements could have been made in the construction or management of hothouses, for example, unless the gardener had extended his enquiries to the manufacture of iron or other metals into sashes; and to the science of chemistry as applied to combustion and the management of heat ?
