Labor Forces

The extremely large images are a little hard to follow, given their size, so I've cropped out the important parts to refer to here with their explanations. 

The first thing to look at on these documents is the totals.  These numbers represent the entire work force (not just the miners) of the Quincy Mine Co. 

1910:  

1915: 

As you can see there were almost 500 fewer people working in 1915 than there were in 1910.  It's feasible that this could have occurred for any number of reasons, but given the time frame, it seems very likely that it would have at least indirectly been a result of implementing the one-man drill.  It's possible that after the stike, even a year after the strike in this case, angry miners refused to go back to work and so the number of workers stayed low.  It's also possible that the company found the drill so useful that they didn't need as many people mining for them. 

Further to the right on the spreadsheet are the totals for previous months' labor.  Here is the column headers from the top with the totals at the bottom.

1915: 

This shows very similar numbers to the previous figures.  The interesting thing to notice is that, while in 1910 they'd pretty much stayed constant in their numbers, in 1915 they were at the highest number of workers they'd had in months.  They hired about 100 new men just that month.  Going back to the previous statements, if the numbers had been lower due to resentful employees looking elsewhere for work, would this be a sign that they were beginning to forgive the companies?  Or were they actually starting to appreciate the drill?  Could they just be giving up on the search for work outside of mining?  Or, if the lower numbers appear because the mining companies didn't need as many workers, could this be a sign that maybe the drill isn't working as well as they'd hoped?  Maybe they had over-estimated the effectiveness of the drill or underestimated how many workers they would need because of the drill, and now they were finding out they were wrong and needed to hire more employees back.

On the next page is an examination of the actual costs of mining with the one-man and the two-man drill.
