yield is somewhat reduced because of the smaller number of canes per 
acre. The heavy weight on one side of the post makes it necessary 
to set the posts deeper or 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 system is 
partially “illustrated in Figure 9. In this case rails are used instead 
of wires. 
There is also considerable diversity of practice as to topping and 
cutting out old canes. Some growers cut out the extra canes in the 
Fic. 6.—Red raspberries trained in accordance with a modification of the weaving sys- 
tem, at Sumner, Wash. ‘The canes, after being bent over and twisted around the 
top wires, are tied to adjoining canes helow the wires 
fall; others leave them until spring. In most cases the canes that are 
left are topped to about 5 or 6 feet in the spring, in the systems of 
training that permit topping. In some of the weaving systems top- 
ping is “obviously out of the question. The soil is given rather shal- 
low cultivation during the growing season and the fields are kept 
clean of weeds until picking time. Nearly all growers fertilize rather 
heavily, using manures of various kinds in addition to moderately 
heavy applications of potash. There is a general belief that potash 
makes the berries firmer and betters the keeping and shipping 
quality, and therefore this one element is seldom omitted. 
Before the harvesting season commences the growers usually go 
through the patches and cut out a considerable portion of the new
