are naturally habituated to an eastern clime, should be 

 so designed, as to offer the least possible obstruction to 

 its entrance : how important, too, that the glass we em- 

 ploy, which in its purest state, offers considerable ob- 

 struction, by refracting the rays of light, should be as 

 transparent and untarnished as possible, so as to admit 

 them as perfectly as can be practicable ; instead of which, 

 it is too often disfigured by an accumulation and deposit 

 of filth, which, to say the least, must materially dimmish 

 their force : how important, moreover, that whatever 

 coverings it may be necessary to employ during the 

 night to prevent the outward radiation ot heat, should be 

 speedily removed in the morning, and kept off as long as 

 they safely may be, in order to permit the inward radia- 

 tion of light. When these matters are all duly attended 

 to, our climate, at least during the winter, still offers ob- 

 struction enough to our success, in its mists, and fogs, its 

 long dark nights, and dismal cloudy days, and therefore 

 wisdom would teach us, to avail ourselves of all which we 

 can grasp, by a course of untiring assiduity, and attention 

 to such apparently trifling matters as these. 



The pruning and training of the plants, are operations, 

 to which it will be necessary to direct attention ; and in 

 the performance of which, the circumstances which may 

 have any influence upon them, as well as the object in 

 view, must be taken into consideration. The plants 

 being intended to occupy a surface of trellis-work in a 

 line nearly parallel with the glass, it will be requisite to 

 train their primary shoots to a sufficient length to reach 

 from the soil to the trellis, before they are what is tech- 

 nically called "stopped;" this operation, by removing 

 the central bud, or axis of developement, induces the 

 buds which are latently formed at the nodes of the 

 branches, to push forth and become the axes of further 

 extension : two or three of the strongest of these lateral 

 shoots situated towards the top of the stem, should
