If Iwere to suggest any improvement at present occurring to my mind, it wouldbe to make the buffers of a compound which would offer a greater resist-ance to compression. The total cost of the apparatus was about |130. The only really novel feature given by me to this accumulator is thepeculiar shape of the brass guide-plates G, G, G, &c., the hubs or fillets ofwhich keep the buffers from coming in contact with the rod B when thebuffers are compressed. If fears were entertained of the accumulator giving way in use, atoggle might be put in the pendant somewhere above the heel of theboom. DEEP-SEA SOUNDING AND DREDGINGV. S. COAST SURVEY PEATE
