The corps of government engineers that arrived last night has already demonstrated the valuable assistance which it is capable of rendering in these times of emergency. With but a few hours rest, those men were up ere sunrise this morning, and by eight o'clock a pontoon bridge had been stretched across the river at Kernville. Acting in conjunction with the Pennsylvania military authorities they are pursuing their labors at various other points, and by sundown it is confidently expected that pontoon bridges will be erected at all places where the necessities of traffic demand. It is the fact, probably not generally known, that the great government of the United States owns only 500 feet of pontoon bridges, and that these are the same that were used by the federal forces in the civil war, twenty-five years ago. The bridges that are to be used at Johnstown were brought from West Point and Willet's Point, where they have been for years used in the ordinary course of instruction in the military and engineer corps. Secret Society Relief. The following official announcements have been made: A Masonic relief committee has been organized and solicits aid for distressed Freemasons and their families. WILLIAM A. DONALDSON, Chairman. OFFICE OF SUPREME COMMANDER, KNIGHTS OF THE MYSTIC CHAIN, WILMINGTON, DEL., June 8, 1889.--In view of the great calamity that has befallen our brothers at Johnstown, Pa., and vicinity, I, H.G. Rettes, Supreme Commander, request that wherever the Order of the Knights of the Mystic Chain exists there be liberal donations made for our afflicted brothers. Affairs at the tremendous stone bridge wreckage pile seem to have resolved themselves into a state of almost hopelessness. It is amazing the routine into which everything has fallen in this particular place. Every morning at seven o'clock a score of Lilliputs come mechanically from huts and tents or the bare hillside, and wearily and weakly go to work clearing away this mass, and at the rate they are now proceeding it will actually be months before the debris is cleared away and the last body found. Fortunately the wind is blowing away from us or we would have olfactory evidence that what is not found is far worse than what has been exposed. Then it may be good business and good policy to have these few workers fool around the edge of the wreckage for five or ten minutes adjusting a dynamite blast, then hastily scramble away and consume as much more time before a tremendous roar announces the ugly work is done, but the onlookers doubt it. Sometimes, when an extra large shot is used, the water, bits of wood and iron, and other shapes more fearfully suggestive, fly directly upward in a solid column at least three hundred feet high, only to fall back again in almost the same spot, to be tugged and pulled at or coaxed to float down an unwilling current that is falling so rapidly now that even this poor mode of egress will soon be shut entirely off.
