have been slightly injured. The espalier trees offer great 

 facility for protection ; and therefore, where spring frosts 

 prevail, the apricot should be so trained. Mats or straw 

 hurdles can be placed against them, both in spring and 

 winter if necessary, with the same ease that a common 

 frame is covered. 



SECTION 7. PRUNING THE NECTARINE. 



The nectarine is but a smooth skinned peach. The 

 trees are so similar in their mode of growth, buds, etc., 

 that they cannot be distinguished from one another, and, 

 therefore, whatever has been said respecting the pruning 

 and treatment of one, applies with equal force to the 

 other. This fruit is so infested with the curculio, that it 

 is almost impossible to obtain a crop that will pay for 

 culture in 'any part of the country in the open ground. Un- 

 less some more effective remedy be discovered than any 

 yet known, it will soon have to retire from the garden, 

 and take up its residence with the foreign grape in glass 

 houses. 



It produces excellent crops trained in espaliers, on a 

 back wall, or a centre trellis of one of those cold graperies 

 now becoming so popular. 



SECTION 8. CULTURE, PRUNING, AND TRAINING HARDY 

 GRAPE VINES* 



The management of our native grapes is exceedingly 

 simple. Immense crops of Catawba and Isabella, and 

 especially the latter, are raised throughout the country 

 in the entire absence of any systematic mode of training 

 or pruning. A single vine in a neighbor's garden, carried 

 to the flat roof of an outbuilding, and allowed to ram- 

 ble there at pleasure, without any care but a very imper-
