194 MOSQUITO ERADICATION 



saw made from the "licker-in" wire. The patented article 

 appears to be made of better steel, and the breaks are not so 

 frequent. However, they are bound to occur with either type, 

 but either can be easily mended by overlapping the ends at the 

 break about 2 inches and tying them together with a strong 

 wire. 



With labor at 30 cents an hour, the cost of sawing probably 

 will average about $5 an acre. However, it is likely that the cost 

 will vary with the type of growth, condition of the pond and many 

 other factors. In any event, it would appear that use of a saw 

 is much cheaper than doing the work by hand. 



In most ca^es, one or two sawings per season should be sufficient 

 for most aquatic plants. It is believed that repeated sawing 

 will ultimately destroy many of the plants.
