taking care to inure the plants for some weeks to an 

 unusually high temperature ; by which means, cauti- 

 ously pursued, we have Uttle doubt that a very much 

 higher temperature might be practised. One piece 

 of caution should here be given, and that is, to keep 

 a thin skreen over them, both during the highest 

 temperatures preceding the operation, and also during 

 the operation itself, which should extend over three 

 days, during which time they may receive many 

 syringings, increasing the temperature slightly each 

 time. After all these points are duly carried out, the 

 temperature and shading should be reduced in a pro- 

 gressive way. Under such high excitement it will 

 require a week or more to bring the plants to their 

 due position. 



The next best process — indeed, perhaps quite equal 

 to the former — is one practised first, we believe, by 

 Baldwin, who was gardener to the Marquis of Hert- 

 ford, at Ragley, about thirty or forty years since. It 

 consists in so preparing a pit, frame, or house, as tha^ 

 the atmosphere for some time shall be strongly im- 

 pregnated with the efflurium of rank dung steam. 

 This is understood to be quite effectual, when pro- 

 perly carried out. The mode in which to perform it 

 scarcely needs description — certainly not to pine- 

 growers ; we, however, write for the uninformed, and 

 therefore beg to say a few words about it. It matters 

 not whether the structure be a house, pit, or frame.
