process should be completed by giving it a full exposure, as frame B; the fruit is readily pro- 

 tected from light frosts, as it can be lowered to the ground, where it is less exposed, as in 

 fig. 2, and if necessary can be easily covered; or, if the ground had been sown with corn or 

 oata as soon as the fruit was sufficiently advanced to admit of elevating the frame, it would 

 form a mat in which the fruit would be imbedded, so as to protect it from light frosts, and 

 would be of service to protect the vine from winter-killing. Thus, by this adjustable frame 

 and method of managing it, tender and oholbe varieties can be raised and ripened in northern 

 latitudes with less trouble and a better prospect of success. The Invention is adapted to a 



variety of forms, and enn be u-cd in several ways: a frame can be so constructed as to turn 



back against buildings, fences, etc., and dispense with legs and (bot-pieoes attached, prop- 

 legs (fig. 2) being used instead; or a row of poets set north and south will BUppoii two rows 

 of frame*, one on each side, made so as to turn back like a trap-door, sis m fig. 1, being held 



in any position by means of suppor te r s attached to the frame on the upper side, the other 

 end being held to the poets by pins passing through both; the frame can be elevated or de- 



prcssed by a series Of hob"- in the sn p port «-r~.

 In relation to the advantage experienoed from the horizontal training of grape-vines, the 



London Gardener's Chronicle states that it has received ample evidence from a well-known 

 English horticulturist bo respect to the benefit derived from this method. On vines which 



has ' n trained horisontally, Borne twenty in number, the mildew has never appeared, while 



the prodnoe has Keen singularly (rood, in an adjoining house, however, in which the more 

 ordinary mode of training was adopted, the vines have been sewerery attacked, and when the 



fir-t evil had been subdued, the disease broke out a M-cond time with e.|iial virulence. 



It is not difficult to explain the increased fruitfulness arising from this method of training,
