structed according to the plans whichyour engineer, Mr. Hayward, has in mind, I am confident it would proveeffective. The site is not unlike one on the upper Clackamas River, in Ore-gon, where a salmon fishway is over a dam of similar height, and it worksvery successfully. I would therefore strongly recommend to your Commission that thefishway be constructed on the south side of the dam, out of reinforcedconcrete. Under these conditions, with the present ledge foundation, Iam confident it will meet with the demands of the river. Yours very truly, Henry OMalley,Field Assistant. Our investigations convinced us that the way should be lo-cated on the south side of the river, which decision was ap-proved by Mr. Perkins. Our engineer was instructed to makesurveys and prepare plans for a fishway, working with Mr.Hale of the Essex Company in order that any objections w^hichmight occur to him could be disposed of as they arose. Manydiflficulties arose as the work progressed, the principal ones

The former will be met by cutting into the ledge,which forms the southerly bank of the river near the dam;the latter, by providing a section built of iron which will spana gap between the upstream end of the way and the dam.This iron section will be swung back out of the way in thelate fall, and put in place late in the spring after the ice hasgone out. The ice will pass over and out through this gap. Thefinal plans were substantially completed, but the specificationshad not been fully drawn up at the close of the year. From the foregoing it will be seen that the way will not becompleted in time to be of use in the spring of 1919. How-ever,
