bog, and connected with the main ilooding canal in order to 

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

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

 dng to connect the check strips with this canal system. In these 

 various canals 13 wooden flumes were built for controlling the 

 water. 



2. Skiujier System InsfalJafion. — On the station bog at East 

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

 inch galvanized piping were installed, 00 feet apart, after the 

 usual manner of Skinner system installation. The longer line 

 was supported at intervals by concrete posts of sufficient height 

 to allow a man to walk beneath the pi[)ing without stooping. 

 The other line was hung in rings suspended from a wire calde 

 drawn taut between two concrete posts. Both of these methods 

 of support have disadvantages. In the former the concrete 

 posts are too numerous and too heavy to give good satisfaction 

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

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

 which makes proper pipe drainage difiicult in freezing weather. 

 Probably a better method than either of these would l^e to sup- 

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

 from the surface of the bog, and placed close enough together to 

 prevent the pipe from sagging perceptibly. Skinner " Outdoor 

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

 running the system was pumped from Spectacle Pond by means 

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

 the bog. It was arranged to pump this water through 350 feefc 

 of 1 "1/4 -inch galvanized piping lief ore it reached the Skinner 

 unions, leading into the ^)4"ii^('li P^pe lines. This ll/4"iiich pipe 

 was, for the most part, buried 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 pump house was arranged to provide for heating 

 the water by pum]iing it first through the cooling jacket of the 

 40 horse-power Fairbanks-Morse engine, and then through a 

 coil in the exhaust pot of the engine. 



For this installation, the Skinner Irrigation Company, Troy,
