Progress of Horticulture for 1847. 5 



the conservatory or greenhouse, accompanied with a record 

 of the daily temperature, &c., we trust has been found to 

 answer the object intended : our diary for the treatment of the 

 grape in the hothouse has been commenced, and, at a future 

 time, we shall give the results in the same style as in the arti- 

 cle alluded to. 



The subject of root-pruning has been fully elucidated in 

 our last volume ; and the most skeptical cannot fail to be in- 

 terested in the discussion, if not convinced of its utility. Re- 

 peated transplantation, to accomplish the desired object of 

 early bearing, is acknowledged by all ; and how far does root- 

 pruning differ from transplantation ? In no respect, save that 

 it is unnecessary, as it often may be inconvenient, to remove 

 the tree. It attains the desired object. The mere removal of 

 the tree would be of no avail if the larger roots were not rent 

 asunder, and root-pruning does this, at the same time reserv- 

 ing, what is most important in transplanting all trees, the 

 fibrous roots. 



The cultivation of the peach in cold houses has been ably 

 treated upon in an article by Mr. Cowan, (p. 204.) The 

 peach crop is so likely to be injured or cut off in the New 

 England States, that its cultivation under glass is increasing. 

 To those who are introducing it into cold houses, either alone, 

 or with the grape, Mr. Cowan's experience will be read with 

 great interest. Root-grafting the peach has been mentioned, 

 by our correspondent. Dr. Philips, (p. 49,) as a very successful 

 mode of propagating it, producing a fine head the first season, 

 and performed with every certainty of success. No great ad- 

 vantage can be gained by this mode of propagation over that 

 of budding. Still it may be practised in some cases where 

 budding has been neglected, and a season saved in securing 

 some new and valuable variety. 



Some new varieties of the strawberry have been recently 

 produced in Ohio, an account of which we have given at p. 

 367. Their qualities have been rather highly praised, but 

 they require the test of longer cultivation to establish their 

 merits. It is somewhat doubtful, however, if they have not 

 been overrated. Some writer, in noticing the report of the 

 Cincinnati Horticultural Society upon Mr. Burr's seedlings, 

 has pertinently asked, "Are they as good as the old sorts'?"
