My party's in power in the city, and it's goin' to undertake a lot of public improvements. Well, I'm tipped off, say, that they're going to lay out a new park at a certain place. I see my opportunity and I take it. I go to that place and I buy up all the land I can in the neighborhood . . . Ain't it perfectly honest to charge a good price and make a profit on my investment and foresight? Of course, it is. Well, that's honest graft.

–G. W. Plunkitt
