 moved by the plow. This must be thoroughly 

 broken up with either the pronged hoe (some 

 times called a potato hook) or the pronged 

 spade ; and which is best we have found to de 

 pend a good deal upon the countryman that 

 uses them. In stiff or stony soils, a stout dou 

 ble pronged hoe, like Fig. 135, is used. This

instrument is also used for working the soil on 

 steep hill-sides, where the plow can not be run. 

 It is in common use by nurserymen, and is a 

 very good implement to have at hand for various 

 purposes. In deplowing in the fall, the un- 

 moved strip along the vines must be moved by 

 hand at the time of plowing, so as to leave the 

 stock of the vines in the open furrow.
