EXPERIMENTAL WORK WITH CRANBERRIES. 65 



experimental bog in East Wareham contained onl.y 21.3 parts of total 

 solids and 12.1 parts of organic solids in 100,000 parts of water at a time 

 when Dr. H. J. Franklin, the superintendent of the bog, deemed the ditch 

 water to be at its normal state, with no irrigation water mixed with it. 

 There was but 0.28 part of total nitrogen in 100,000 parts, and bare traces 

 uf phosphates and potash in this water. 



The seepage water, which is practically the same thing as the saturated 

 soil water from the interior of the peat, is noticeably uniform in compo- 

 sition throughout the season, and the average composition for 1912 is 

 very close to that of 1911, published in the twenty-fourth annual report.'
