Vintage work crew photos

1912! My house was already 11 years old. A quick google says the 'gas' is produced burning coke to obtain fuel, mainly for illumination. But the truck load includes bags, making home equipment unclear.
Now if, I don't know who, someone was to say the bags ARE gas, we'd have a field day punting that around.

One more of Jon's streak, finding really high quality black and white photos. Nothing details subjects like good black and white.
