His father had been a veterinary surgeon who had kept a livery stable near by, on California Street, and Marcus's knowledge of the diseases of domestic animals had been picked up in a haphazard way, much after the manner of McTeague's education.

Somehow he managed to impress Old Grannis, a gentle, simple-minded old man, with a sense of his fitness, bewildering him with a torrent of empty phrases that he delivered with fierce gestures and with a manner of the greatest conviction.
"You'd better come along with me, Mac," observed Marcus.

"We'll get the duck's dog, and then we'll take a little walk, huh?
You got nothun to do.

Come along." McTeague went out with him, and the two friends proceeded up to the avenue to the house where the dog was to be found.

It was a huge mansion-like place, set in an enormous garden that occupied a whole third of the block; and while Marcus tramped up the front steps and rang the doorbell boldly, to show his independence, McTeague remained below on the sidewalk, gazing stupidly at the curtained windows, the marble steps, and the bronze griffins, troubled and a little confused by all this massive luxury.
After they had taken the dog to the hospital and had left him to whimper behind the wire netting, they returned to Polk Street and had a glass of beer in the back room of Joe Frenna's corner grocery.
Ever since they had left the huge mansion on the avenue, Marcus had been attacking the capitalists, a class which he pretended to execrate.
