Fig. 15 shows the arrangement of the ballast piping as well as the de- tails for same. This pumping machine, Fig. 16, dif- fers from all others in this respect: that the water from each compart- ment is handled by separate pump with the old pumps. The time consumed in pumping out the water ballast is largely done after the water goes down to the top of the deep floors, as the water will not run through the limbers fast enough to supply the capacity of the pump, and if one compartment goes dry, it breaks the vacuum of the suction, and _ prevents the pump from working. In this system if one pump is get- ' tine water, it primes all of the other _ pumps automatically and dries out the ae compartments without any attention on the part of the engineer, and does mM '2 16ss than- one-fourth of 'the time occupied by any other system. ahe engineers operating these pumps are very much elated over the performance, as it saves them a great amount of work. This, itself, is the best evidence that the right thing has been done in adopting this system. It is the general opinion of engi- neers, who have looked into this mat- ter, that the pumps on these general lines have got to be adopted to re- 'move 'the water ballast. in a' short space of time. - Steamers Sierra, Chas. Hubbard and Smith Thompson have this sys- tem and The Great Lakes Engineer- ing Works will put it into two new vessels which they are now building. The following is the details of work done by the patent ballast pump system on the steamer Charles Hub- bard, April 23, 1907: BALLAST PUMPS.
