ing canes may be kept erect by tying them to a single wire which is 

 stretched about four feet high on posts set about 20 or 30 feet apart in the 

 rows ; or two wires, one at three feet and one at five feet, may be used in 

 making this kind of a trellis, and the canes tied to both the upper and 

 lower wires. A very simple and satisfactory form of trellis may be made 

 by nailing cross pieces about fifteen inches in length to posts. Wires are 

 stretched from the ends of the cross pieces, one wire on each side. The 

 plants grow up between the wires and are supported by them. When the 

 black raspberries are properly summer pruned, the canes become very 

 sturdy and self-supporting and a trellis is considered unnecessary. Tt is

sometimes an advantage to place a stake near each plant and tie the canes 

 to it, or if desired the two wire trellis just described will be found very 

 satisfactory. 



HARVESTING 



The raspberries should be handled carefully to avoid bruising. The 

 bushes should be picked over often. During the height of the season, pick- 

 ing at least every other day is necessary. The berries should be firm but 

 not over ripe to reach the market in good condition. In the home garden 

 the fruit may be left on the bushes until quite ripe and a much higher 

 flavor and quality will develop. Never pick when wet unless for imme-
