MR. RICHARDS. The sheet piling was 4 inches thick, usually about 8 inches wide, grooved and splined. It was driven between two waling pieces laid lengthwise of the trench, and as the trench was about 35 feet deep and in very fine sand at the bottom, it was, of course, rather difficult to use an ordinary piledriver for the reason that its operation would shake the sides of the trench so they would be liable to cave in; and, furthermore, every brace would have to be moved when you moved your piledriver along, and there were a good many of them in a 35-foot trench. So we tried a steam drill, first with a hammer we made ourselves, and afterwards with one which was made by the company. So long as the drill lasted we were very successful in driving the piles, that is, the strokes of the hammer were so near together that the pile didn't have time to stick, or, in other words, the sand didn't have time to settle around it, but, having once started, the pile kept going. The drill, of course, was made for a different purpose, and it broke continually, so we finally had to give it up and use the ordinary pile-driver. I think a more strongly made drill would work very nicely, and I understand that they make one now especially for driving piles.

MR. FULLER. How heavy was the hammer you used?

MR. RICHARDS. My impression is it wasn't more than 10 or 15 pounds; it was very light.

A MEMBER. I believe Mr. Richards has some very interesting information with reference to an impulse wheel and rotary pump, and I should like to have him describe that to us in a few words, if he will.

MR. RICHARDS. I am not quite ready to describe the pumping station, as it is not finished yet, and I don't know exactly what it will do. I should prefer to wait until I have tried it. However, I can say that we were very peculiarly situated in having a water supply of such a quality that we couldn't use it for anything else but power, so we use it for power to pump to our high service. We have about 120 feet head, and with that head we use a jet impulse wheel, a Pelton wheel, in one case coupled directly to a rotary pump. We have another wheel which is coupled on to an ordinary triplex pump. So far it appears to work very nicely. It pumps against something like 60 pounds. When it is tested. I shall be pleased to describe it.

On motion of Mr. Coggeshall the Secretary was directed to cast one ballot in favor of the applicants, which he did, and they were thereupon declared elected members of the Association.

MR. CHARLES W. SHERMAN. In view of the fact that so many of our members had such a pleasant trip this morning through the East Boston tunnel, I think a vote of thanks to the chief engineer and to the Boston Transit Commission will not be out of place, and I therefore move the adoption of the following vote: Voted, That the thanks of the Association be given to Mr. Howard A. Carson, chief engineer, and through him to the Boston Transit Commission, for courtesies extended to us at our visit to the East Boston tunnel this forenoon.

Adopted.

MR. HENRY F. JENKS. I wish to say a few words, Mr. President, and if what I am about to say does not seem to be proper I had rather not be called to order until after I get through. Many of us who are now here remember our trip to Montreal last September, and we know that it must have required a great deal of
