THE CELILO CANAL 



At a cost of six millions in money and 

 the labor of hundreds of men continu- 

 ously for almost ten years, Uncle Sam 

 has at last completed the Celilo canal in 

 Oregon on the Columbia River. The 

 big ditch was formally opened May 5th 

 by a celebration which actually began 

 May ist and did not conclude until May 

 8th. The celebration was a progressive 

 affair, beginning at Lewiston, Idaho, 500 

 miles from the river's mouth and the 

 present head of navigation on the Snake 

 River, the Columbia's principal upper 



tributary, and continued on down river 

 to Portland on the Willamette River, the 

 principal stream emptying in the Colum-

 pating in the several programs traveled 

 by steamboat in honor of the opening 

 of the great waterway the second 

 largest in America through the various 

 locks and the entire length of the remark- 

 able canal just then completed. 



Celilo canal is one of the marvels of 

 jnodern construction. It is eight miles 

 long and the greatest part of it was 

 bored through solid lava rock stone so 

 hard that the construction cost averaged 

 almost $1,000,000 per mile. At some 

 points a sheer cut of 70 feet through live 

 rock was necessary. All types of wall 

 construction obtained, from the rein- 

 forced concrete to ordinary masonry 

 and dry masonry. 



At several points workmen found the 

 charred trunks of trees buried deep in 

 the lava where they had been over- 

 whelmed centuries ago when the great 

 stream of molten rock flowed across the
