THE IRRIGATION AGE. 



A GREAT IMPROVEMENT IN FLUME 

 CONSTRUCTION. 



In the great strides that are being made through- 

 out the world in the construction of power and irriga- 

 tion canals, it is probable that no improvement has 

 done more to facilitate this work than the Maginnis 

 Clamp Joint or Splice, which has made it possible to 

 substitute steel for wood in flume construction. The 

 Maginnis Galvanized Steel 'Flume has passed the experi- 

 mental stage and is now recommended and used by all 

 engineers and canal builders who have had experience 

 with it, or who have seen it used. 



can handle a wrench. When once in place it is abso- 

 lutely water tight, and will last a life time. The sheets 

 are so bundled for shipment that they occupy but little 

 space and can be easily freighted to interior points by 

 team or pack horses if required. It is shipped on all 

 railroads as third class matter in less than cars, and 

 fifth class in car loads. 



The flume shown in the illustration on this page 

 was erected in the Big Horn Basin of Wyoming, 90 

 miles from a railroad. It has a perimeter of 12 feet, is 

 2,498 feet long, is erected on a twenty degree curve, 

 and is carrying 110 cubic feet of water per second. The 

 trestle has a maximum height of fifty feet. This flume

The first steel flume that was constructed under 

 this system was put in use in the spring of 1902 and is 

 now carrying water for the sixth season without a leak 

 or break, and has not cost the owner one dollar in time 

 or money during the six seasons it has been in opera- 

 tion. From all appearances the flume will continue its 

 good work for a life time. Engineers differ in their 

 opinions as to the life of the steel flume, some placing 

 it at twenty-five, some at thirty, and others at fifty years. 

 The economy in the use of steel in flume construction 

 is thus made apparent to every one who has had experi- 

 ence with the wooden structures, and the constant bill 

 of expense required to keep them in condition to carry 

 water. 



The steel flume is made in all sizes from 24 to 240- 

 inch perimeter, wh'ich will c&rry from ] to 500 cubic 

 feet of water per second, and is put together in sections 

 30 inches long, by a beaded clamp joint, without, rivets 

 or solder, and can be put in place by any laborer who 



has now been in use two years, and is in every way as 

 perfect as when first erected. It has remained dry for 

 seven months of each year, exposed to the sun and wind 

 without the least injury. This flume will continue to do- 

 this work, carrying the water required during the irri- 

 gation season, and remaining dry and exposed to all 

 climatic conditions during the remainder of the year, 

 without care and expense, and will last as long as the 

 substructure will stand. The first steel flume was put 

 in by this company in 1904 and proved so satisfactory 

 that the one here shown was erected by the same com- 

 pany in 1906, and this year a third flume has been 

 erected for them with a 14-foot perimeter, which shows 

 their feeling toward steel flumes. 



The Maginnis Galvanized Steel Flume is manufac- 

 tured by Mr. P. Maginnis at Kimball, Neb. The sales 

 department is in charge of T. C. Egleston. 303 Railway 

 Exchange building, Denver, Colo., who will gladly reply
