MANY THOUSAND
 TONS 0F WASTE
 ROCK TAKE DIP
Alaska Juneau Conveyor Wrecked on New Break
 water This Morning.

Rock estimated as weighing 75,000 tons, disappeared beneath the wat CTS of Gastineau Channel at an early hour this morning from the end Of the Aaska-Juneau rock dump and as it slid wrecked the trestle and conveyor for a distance of 150 feet, causing damage amounting to more than a thousand dollars.
 The accident happened at the new breakwater being built by the Al aska-Juneau Gold Mining Company for the protection of the Juneau har- bor that is made of waste rock that is sorted from the Alaska Juneau mine ore.
 Before the slide occurred the breakwater extended out from shore for about 300 feet; now a scant 150 feet remains at it's previous height, while perhaps another 100 feet re- mains in sight, but with it's top just about at water level. About 50 feet of the trestle carrying the rock con veyor remains intact, while the rest of the massive structure is twisted mass of iron and wood.
 A repair crew from the Alaska Juneau was on the job early this morning starting repair work on the wrecked conveyor. Track men were changing tracks so that the rock can be dumped on a trestle parallel with the beach line The car carrying waste may be running late today, while in the course of a few days the conveyor will be running, bit dumping rock much nearer to shore than before.
 Second Slide
 Several weeks ago many thousand tons of rock went out of sight, a exactly the same place. At that time it became necessary to move the conveyo or back slightly The pile was brorsht back to it's previous size and one move made since.
 Brought By Tram
 The waste rock making up the breakwater is let down in cars from the Alaska-Juneau mill on the side hill by a cable tram After reaching a position parallel to the beach the cars are taken by an electric switch engine and shunted around. Inc rCck from them is dumped into q hopper and onto a conveyor that car ries it several hundred feet out into the channel and dumps it. As i; WAS dumped it formed a perfect rock pier and breakwater. It was the end of this breakwater that disappeared.
 All Right Last Night
 Two shifts are employed in handl- ing this waste rock The afterICoa shift quit at II last night and every thing was all right at that time From checking up it is estimated that the slide occurred at about o'clock this morning. No absolute reason is given for the accident. al tiouS. many theories are advanced One is that strong current Under mined the pile of rock, causing it to torple ever and spread out. An ether IS that there is a heavy layer of muck on the bottom which breaks th' ou2h to bedrock with the Srca weight.
 No Delay
 According to P. R. Bradley, con sulting engineer for the Alaska-Ju- neau Gold Mining Company, there will be no delay in mining operations or at the mill on account of the ac- cident. The bin at the bill is large enough to take care of the surplus rock until the first dump is made ready for use and before the dump ing space there is filled up the con veyor will be in working order again
 Much Regretted
 The disappearance of the rock is much regretted locally as it's pres ence was rapidly building up a fine harbor. It undoes the work of sev- eral months and makes it just that much longer for the completion of the breakwater Four thousand tons of waste was being dumped each day
