acre. The heavy weight on one side of the post makes it necessary 

 to set the posts deeper or to have them closer together than in other 

 systems. "Where hop poles or rails are available at a low cost they 

 are often used in place of the upper wires, the rails bearing the weight 

 of the loaded canes thus providing a larger surface and reducing the 

 danger of having the canes break at this point. The Streblow sys- 

 tem is partially illustrated in figure 9. In this case rails are used 

 instead of wires. 



Fig. 8.- K<.'<1 raspberries trained in accordance with the divided row system, the canes 

 beini; tied to wires on either side or held in place by an outside wire. Topping may 

 be practiced, if d'-sired. 



There bs also considerable diversity of practice as regards topping 

 and cutting out the old canes. Some growers cut out the extra canes 

 in tli<- fall, while others Leave them until spring. In most cases the 

 canes that are left are usually topped to about 5 or 6 feet in the 

 spring; thai i-. in the systems of training that permit topping. In 

 some of the weaving systems topping is obviously out of the 

 question. The soil is given rather shallow cultivation during the 

 growing season and the fields are kepi clean of weeds until picking 

 time. Nearly all growers fertilize rather heavily, using manures of 

 rarious kinds in addition to moderately heavy applications of potash.
