A recent issue of the " Pall Mall Gazette" contains an interesting letter_from Captain F. 0. de Cres-pigmy of the 3rd Essex suggesting the the use of trench periscopes. He points, out that hundreds of lives are being sacrificed by men exposing themselves for observation purposes and indicates, what he considers would be a remedy, namely the use of periscopes of, say, three feet long, constructed of tin or pre ferably aluminium and painted khaki colour, with couple of spare. glasses for replacements attached at the lower end. The instrument could be very cheaply made and would in the writer's opinion be of great practical value. "Here is," he writes, "an unpre cedented opportunity for some patrio tic rin of instrument makers immediately to put such an instrument on the market." It will be interesting to see whether any of the. manufacturers appealed to are willing to experiment. Captain de Crespigny does not pretend to have thrown out more an an idea wi certainly sounds practical enough.
