Remarks on the cultivation of the Filbert. 57 



varieties of fruits have been produced by the skill of the hor- 

 ticulturist, from the crude stock which nature has placed in 

 his hands, and they need his continued assistance, to prevent 

 them from deteriorating into an inferior or worthless state. 



Forest trees and shrubs require the same attention, as re- 

 gards deep planting, as fruit trees; they are as easily affected 

 by mismanagement, and though there is no crop of fruit to 

 lose, no lover of garden scenery wishes to see them linger- 

 ing along in a feeble and unhealthy state. 



The production of new varieties by cross impregnation, 

 grafting, budding, &c., and the renovation of trees, are sub- 

 jects deserving of separate notice, and we shall endeavor to 

 offer some observations hereafter upon each. 



Art. III. Remarks on the cultivation of the Filbert, (Cory- 

 lus avenella var.) By A. J. Downing, Botanic Garden 

 and Nurseries, Newburgb, N. Y. 



The filbert is one of the finest nuts, and although great 

 quantities of the fruit are imported, and sold in the fruit shops 

 annually, there are scarcely any, as yet, cultivated in the Unit- 

 ed States. A sterile variety of the English filbert may be 

 seen in many of our gardens, which rarely produces any fruit; 

 but the finer sorts, which thrive luxuriantly, and bear most 

 abundantly in this climate, are scarcely known in cultivation. 

 Nothing can well be easier than the cultivation of this shrub 

 or tree, and we are confident that were the merits of the bet- 

 ter varieties generally known, no garden would be considered 

 complete without them. A (ew years since, we imported 

 small plants of the most celebrated English varieties, and 

 have, without the least attention to pruning, realized quite an 

 abundant crop of fine nuts, for two years past, which are quite 

 an acceptable addition to the dessert. 



Among the finest of these varieties are the Frizzled, the 

 red Kernel, the Northampton Prolific, the Cobnut, and the
