On a piece of sandy loam, having a Southern aspect, alternate 

 rows of the varieties named below were planted three and oue-half 

 feet apart — one being "trenched," the other planted in a furrow. 

 The rows "trenched" were plowed about a foot wide and eight inches 

 deep, after which the soil in the bottom of the furrow was loosened 

 and pulverized, some earth being worked back into the furrow, the 

 "seed"cut into two eyes was then planted one foot apart in the row. 

 The pieces were covered to a depth of about two inches when a 

 complete fertilizer at the rate of 1,000 pounds to the acre was scat- 

 tered in the trenches, and the trenches were filled. The other rows 

 were simply plowed, the seed pieces dropped and covered, when 

 the same amount of fertilizer as before was scattered on the sur- 

 face. As soon as the young shoots appeared above the surface, 

 the smoothing harrow was used, and thorough culture was given 

 until about the middle of JuW when the vines covered the ground 

 sufficiently to keep the weeds down and serve as a mulch for them- 

 selves. 



The comparative results are shown in the accompanying table :
