At the dredge-reel the arrangement was similar; the man standing at.that point attended the throttle, the friction-lever, the clutch-lever, and thereversing-lever. In addition, he could guide the rope on the reel in caseof emergency. The drawings for the hoisting-engine were made by Mr. Earle C.Bacon, of Messrs. Copeland & Bacon, 85 Liberty street, New York. Istated to him the size of cylinders, relation of gears, the action requiredof the several parts, the positions of levers and throttle—in general termsthe requirements; and he then worked the whole out in his own way—noeasy matter, as may easily be seen—using his patent trunk-cylinders; andso successful was he in the design that not a single fault has been foundwith his engine by those who have used it. He worked out the form ofthe winding-engine at the reel, and with the same success. U. S. COAST SURVEY. PLATE 28. DEEP-SEA SOUNDING AND DREDGING.

THE IMPROVED TRAWL SHOWN AS HAVING TRIPPED AFTER FOULING WITH ROUGH BOTTOM.Heliotype Printing Co., 220 Devonshire St., Boston DREDGING AND TRAWLING—APPARATUS AND METHODS. 143 On this cruise the methods adopted for planting the dredge and trawlwere practically the same as on the previous cruise, but as regards theworking of the machinery and gear Professor Agassiz and CommanderBartlett state that the drawbacks which had been experienced before werenot met with at all. The work proceeded smoothly, and without accidentwhich could in any way be laid to the agency of the machinery. Therope could be wound upon the reel wath nice regularity. The operation of paying out rope was managed as follows: the dredgeor trawl being shackled to the rope and over the side, the counter set,the friction-brake at the reel in hand, and the engine at the reel out ofgear, the brake at the hoisting-engine was thrown out of action andlocked; the winch-head was clutched to the gears and the link adjusted forre
