Just to the right of the shovel records, and below the record for drill gang No. 2, is the heading "_ng.tr. # 1_;" and the men whose numbers are under this heading are engaged in laying and repairing the narrow─gauge track for the dump trains from shovel No. 1. Just below the middle of the page, is a list of names and numbers utterly unintelligible to anyone but the one who made it. The facts are these: _Donovan_ is the man who looked after the storage of powder; within the bracket, _Nick_ (the time─keeper, not knowing the last name, used his number, as well as the part of the name that he knows) is the blacksmith; and No. 72 is his helper; No. 118 helped the blacksmith for two hours, having been taken from the narrow─gauge track gang. The time─keeper had to depend entirely upon the blacksmith telling him this, or his record would have been incomplete. The next three men whose names appear in this column were engaged upon repairing a 6─inch pipe line; and the next two pairs within brackets, marked No. 2 and No. 1, are the pipe─fitters for the drill gangs and shovels No. 2 and No. 1 respectively. DISTRIBUTION FROM TIME─KEEPER'S NOTEBOOK The time─keeper, having taken his notes over the entire job, sends them to the office so that the time may be posted for each man, and the distribution made. The time─keeper goes over his notes, and picks out the items that are chargeable to drilling. In gang No. 2, there are 6 drillers at 30 cents per hour; 6 helpers, 4 muckers, 1 man carrying bits, and one fireman's helper, all at 17 cents, and one fireman at 25 cents. From the note at the bottom of the page, he knows (although no one else would) that _Lear_ at 20 cents and No. 278 at 17 cents, were also with this gang. This, with the foreman at $3.50 per day, figures to $29.08. These are the charges that go directly to drilling, being the cost of time of the men actually engaged upon that operation and nothing else. But besides this, there must be apportioned to this cost a certain part of the Superintendent's salary, a portion of the labor on the 6─inch water pipe and the whole water system, a portion of the time of the blacksmith, the watchman, the storekeeper, the time─keeper, clerks, the water boy, and numerous other items.
