bog, and connected with tlic main flooding canal in order to 

 flow and drain these areas. Short side canals were dng to con- 

 nect this canal with the separate areas. Small canals were also 

 dng to connect the cluK'k strips with this canal system. In these 

 varions canals 13 wooden ilnmes were bnilt for controlling the 

 water. 



2. Skinner Si/sfmi InsfaJhdion. — On the station hog at East 

 Wareham two lines, 70 and 100 feet long, respectively, of %- 

 inch galvanized ]ni)ing were installed, 00 feet apart, after the 

 nsnal manner of Skinner system installation. The longer line 

 was snpported at intervals by concrete posts of sufficient height 

 to allow a man to walk beneath the piping withont stooping. 

 The other line was hnng in rings snspended from a wire cable 

 drawn tant between two concrete posts. Both of these methods 

 of snpport have disadvantages. In the former the concrete 

 posts are too nnmerons and too heavy to give good satisfaction 

 on the nsnally soft bottom of a cranberry bog. In the latter it 

 is hard to get rid of a certain amonnt of sag in the piping, 

 which makes proper pipe drainage difficnlt in freezing weather. 

 Probably a better method than either of these would be to snp- 

 port the piping on wooden posts reaching up only a foot or two 

 from the snrface of the bog, and placed close enongh together to 

 prevent the pipe from sagging perceptibly. Skinner " Ontdoor 

 Xo. 2 " nozzles were nsed in this installation. The water for 

 rnnning the system was pumped from Spectacle Pond by means 

 of a Myer's pnmp driven from the big engine used in flooding 

 the bog. It was arranged to pnmp this water through 350 feet 

 of li/l-iiich galvanized i>iping before it reached the Skinner 

 unions, leading into the ^-inch pipe lines. This li4"ii^^^i pip^^ 

 was, for the most part, bnried in the ground. A special device 

 driven by water pressure, for turning the pipes back and forth 

 so as to throw the water on both sides, was also installed. The 

 piping in the pnmp house was arranged to provide for heating 

 the water by puminng it first through the cooling jacket of the 

 40 horse-power Fairbanks-]\Iorse engine, and then through a 

 coil in the exhaust pot of the engine.
