working his speed up to nearly full speed. Many readers will no doubt remember several other cases. of broken shafts brought before the no- tice of the institute from time to time. Passing on to the condenser and pumps there is no part of our engines that we can diagnose faults from symptoms so readily. Let us suppose upon entering the engine room we find the vacuum gage going back to 18 in. or 20 in, vacuum, and the engine slowly down. Our first duty should be to ascertain that the circulating pump is doing its duty correctly by getting the temperature of the cir- culating water. If very cold, then I THe Marine REVIEW should assume that one of the di- vision plates in water way of the con- densers had given way, and the water was not going through the tubes; this would give a cold discharge and loss of vacuum, with one end of the con- denser fairly hot. Again, say we find the temperature of the discharge hotter than normal but feeding going on regularly. I should at once Say there was some- thing wrong with the circulating pump. We should then set to work and find the fault. Should the air pump give out, what are the first indications of it going wrong? It would show a loss of vacuum, an intermittent feeding, with occasionally overflowing from the hot well. We should experience little or no trouble with leaky foot valves if the head and bucket were tight and in good working order. Should the foot valve or valves give out and air is being admitted under the head valve for cushioning pur- poses, I suggest that the air valve be shut down so that the pump will make better vacuum on tthe downstroke 'than in the condenser. If the head valves are giving out, I suggest that the foot valves be robbed if possible to suppty the head valves: Should the bucket become broken I would suggest mak- ing a wooden bucket and packing it in the ordinary manner with manilla rope. Ferry Steamer Finnieston. There is herewith illustrated the new elevating vehicular ferry-steamer Finnieston No. 1, recently constructed by Messrs. Ferguson Bros., ship build- ers and engineers, Port Glasgow, for the trustees of the Clyde Navigation, under the direction of G. H. Bax- ter, mechanical engineer. The vessel was launched with machinery aboard and steam up; the illustration is from a photograph taken immediately after the launch. This is the second ferry of this type built for the Clyde trust. The first was constructed in 1890. It has since done good service, and justified the building of this second and larger vessel which will be used at the same point--at Finneston, about a mile west of Glasgow bridge, while the old ferry will be transferred to Pointhouse, a mile. further west, where a floating bridge has hitherto served for vehicular traffic between the suburban burghs of Patrick and Govan. We give in parallel columns the dimensions of the new and the old boats: "Finnieston" "Finnieston'"' of 1908. of 1890. Renoth 6.8 s eS 104 ft. 80 ft. Breadth ie a 45 ft. 43 ft.
