1903.] MARINE REVIEW AND MARINE RECORD. 33 THE CHICAGO PLUG DRILL. The Chicago plug drill, made by the Chicago Pneumatic Tool Co., consists of an arrangement whereby the regular No. 1 Boyer hammer is equipped with a drill and a rotating device, which automatically turns the drill while the hammer is delivering the blows. It has been used with exceed: ingly gratifying results in a large number of.the quar- ries and cutting sheds throughout the country and has demonstrated very con- clusively that it is a decided success. In construction it is very simple, requiring very little repairing, and as all the parts are readily ac- cessible, it can, of course, be very easily cleaned. The drill weighs 18 lbs. com- plete, consumes 20 cu. ft. of free air per minute at 80 lbs. pressure and will drill a hole 58 in. in diameter by 3 in. deep in any kind of stone. In one instance a hole of this size, 3 in. by 54 in., was drilled in 20 seconds in moderately hard _ stone, which is considered a very remarkable record. One very advantageous feature about this machine is that it will drill in all classes of stone with equal rapidity, simply requiring in a different dressing of the drill blanks. Te drills which are used in them do not require re-sharpening nearly as frequently as in hand drills on account of the light, rapid blow which they strike. In some instances as high as twenty holes have been drilled without re-sharpening the drill. In all classes of plug and feather work these drills have been found invalua- ble, and it is a very practical machine for either top or side line work, its weight being so slight that but one hand-is required to operate it. The company says that results thus far have con- clusively proved that it is without doubt the most satisfactory rock drill on the market today. Chicago Plug Drill. LAKE SUBMARINE BOAT' PROTECTOR. Upon the invitation of the inventor, Simon Lake, a party of newspaper men inspected the latest specimen of the Lake sub- marine boat, the Protector, at Bridgeport, last week. The Lake . type of boat differs from that with which the public is already familiar in several respects. It has an air-tight compartment out forward, from which a trap door opens into the water below. By that means a submarine diver could cut a telegraph cable, sever the connection between shore batteries and mines in a harbor,. and perform other feats that would be serviceable in war. Sev- eral guests went into this air chamber to watch a diver make his exit and return. An alteration of the original design of the Lake submarine gives it three launching tubes for Whitehead torpedoes. One of these missiles, not loaded for service, was ejected for pur- pose of illustration. Lieut. John Halligan, of the United States navy, has been assigned to duty temporarily on the Protector, the case of the harder stone " and is in charge of torpedo operations. Both he and R. C. Sker- rett, formerly:in the naval service, assisted Mr. Lake in explaining the many interesting features of the boat. One of the most im- portant of these is the omniscope, wherewith the officer in com- mand is able to obtain a view of the enemy and get his bearings. The device rises from the conning tower, and has a more com- plete sweep of the horizon than other optical apparatus perform- ing the same function. Still another novelty is the provision made for supplementing the usual agencies that depress and raise the boat in the sea. Besides employing water storage and pumps and a horizontal rudder, Mr, Lake has two long, narrow sheets of metal on each side of, and exterior to, the hull. These hydrop- lanes normally remain exactly horizontal. By lifting or lowering their forward ends slightly when they are submerged he alters the level of the boat itself, . INJURIES TO THE MASSACHUSETTS. Real Admiral Rodgers, commandant of the New York navy yard, has reported as follows regarding the injuries to the battle- ship Massachusetts : _. "Careful examination of the Massachusetts in dock shows injuries to docking keels and bottom plating, substantially as re- ported from Bar harbor. Considering character and extent of in- juries, temporary repdirs inadvisable. Injuries can be thoroughly and permanently repaired in seventy working days at estimated cost of labor, $36,000; material, $6,000." s Admiral Rodgers also recommended that the Massachusetts be kept in No. 3. dock, and that the repairs to her bottom be im- mediately undertaken. The other vessels of the squadron ordered to New York for repairs should, in his opinion, be docked in No. 2 dock, except the Indiana, which is too large. The bureau of construction and repairs recommended to the secretary of the navy that permanent repairs be made on the Massachusetts at the cost estimated, and Acting Secretary Darling approved the recommendation. The ,distribution of the ships of the North Atlantic station for repairs at navy yards, preparatory to the winter maneuvers, has been made by Acting Secretary.of the Navy Darling. . The Nashville, Arethusa, Scorpion, Newport and Hist have been as- signed to the yard at Boston. The New York navy yard will have the Indiana,: Illinois, Massachusetts, Kearsarge, Alabama, Texas, Chicago, Dolphin and Baltimore. The Norfolk yard will get the Olympia, Caesar, Lebanon, Marcellus, Leonidas, Chaun- - cey, Worden, Barry, Bainbridge, Decatur, Dale, Whipple, Trux- ton, Stewart and Lawrence. The Yankee, Hartford, Panther and Prairie will go to the League Island navy yard; the Vixen, Po- tomac, Essex and Monongahela to Portsmouth; and the Ban- croft and Wasp to Pensacola. The work to be done on most of these vessels is of a minor character. On the Massachusetts, Chicago, Barry and Decatur, however, the work will amount to a thorough overhauling. It is announced that the Commercial Pacific cables, operated © in connection with the land lines of the Postal Telegraph Co}, are now open for business to and from the Philippines, Ladrone - islands, China, Japan and Corea. The rate per word between points named and San Francisco will be as follows: Midway, 60 cents; Guam. 85 cents; Manila and Luzon islands, $1.05; all other Philippine islands, $1.50; Hong Kong, $1.10; China, $1.10; | Macao, $1.15; Japan, $1.41; Chemulpo, Fuzan and Seoul, an Corea, $1.41; other places in Corea, $1.49; Formosa, $1.41. .
