minimum thickness of consider should be adopted for the top of the dam.

Design B, it is proposed to increase the thickness of the extension to 2010.

It will be seen that in both designs when the water level is level with the top of the dam (exclusive of parapet) the line of resistance deviates slightly outside the middle third. Though somewhat less in design B, the advantage gained is not in my opinion commensurate with the additional cost of the extension.

The maximum compression reaches nearly ten tons in both cases. This is somewhat in excess of what I should recommend in the case of constructing a new dam, but in the present case, the deepest part of the dam is on a rock foundation, and as will be seen from the elevation, it is a very short length.

I am therefore inclined to recommend the adoption of design A, by which an increase of 10 feet in the depth of the reservoir will be obtained, and an additional two feet or so might be arranged for by furnishing the new overflow with stopboards or sluices to be opened during floods.

I request that this report, together with the accompanying three tracings, may be forwarded as soon as practicable to Mr. Chadaick, Consulting Engineer, and be requested to telegraph (if he approves) his
