appropriate, often injures the appearance of the grounds, and 

 is, after a few years, vmder the necessity of cutting down 

 and planting anew. The greatest error is in not setting out 

 more evergreen shrubs, such as Kalmias, Rhododendrons, &c. 



COMMERCIAL GARDENING. 



There is but little change to note in commercial gardening. 

 The demand for trees continues active, and the various nur- 

 series appear to improve in the arrangement and good keeping 

 of their grounds. The onward progress of horticultural art 

 demands more of system than has hitherto obtained among 

 the majority of nurserymen ; and, as a good reputation is the 

 most valuable capital he can possess, it becomes an object of 

 some importance to obtain it. In consequence of this, we 

 now jfind in every good nursery plantations of bearing trees, 

 and specimens of beautiful shrubs, for the inspection of the 

 purchaser and the information of the proprietor. Without 

 such, it would be almost impossible, at the present day, to 

 succeed. 



The number of new fruits is rapidly increasing ; and, al- 

 though some of the older sorts have been struck off by the 

 Pomological Congress, yet the accessions have been large, 

 and the catalogue must continue to increase until an oppor- 

 tunity has been afforded to fully test their qualities ; but, as 

 this is a work of time, it will require a long period before 

 they can be placed on the rejected list. Nurserymen should 

 feel it a duty they owe to themselves, as well as the public, 

 to try all, and retain only the good. In this way many 

 worthless varieties will be eventually discarded from culti- 

 vation. 



In New York, Messrs. Prince, Parsons, Thorburn, Hogg, 

 and Dunlap, have made additions to their establishments, Mr. 

 Thorburn having erected a new house for the cultivation of 

 roses. 



Around Boston there is some improvement. Messrs. Hov- 

 ey & Co. have just completed a very large and fine plant- 

 house, — ninety-six feet long, thirty wide, and sixteen high, — 

 and now nearly filled with plants. Our Horticultural Reports
