In the land wall are built 10 openings 3 ft. X 3ft. 6 in., through which the water passes from the fillingculvert into the lock chamber. From here it passesthrough the lower recess by means of seven openingssimilar in size and location to those in the upper recess,into the emptying culvert, whence it flows into the lowerpool. The land wall, including the walls of the gate re-cess, will have a development of 1,170 ft., and will con-tain about 6,000 yds. of masonry. The river wall will be. 6taver Dm.\Ohio Rive(\. The use of gas engines is by no means so extensive inthis country as in England, where they are found at workin many different places. Here they are generally regard-ed as of service for light work only, and it is with somesurprise that we note the advertisement of an Englishfirm, which keeps all sizes up to 40 in stock, andoffers to furnish single engines of any size up to 250 much exceeds the capacity of any gas engine builtuntil very recently. Work has been begun on the new dam and lock onthe Ohio River at Vanport, near Beaver, commonly calledthe Beaver Dam. This will finally be No. 6 in the seriesof dams proposed to improve the navigation of the river,of which the Davis Island Dam was the first. The gen-eral plan of the dam and lock, as they will appear whenfinished, is shown in the accompanying sketch, for whichwe are indebted to the Pittsburgh Chronicle-Telegraph. A special feature is the lock, whic
