There were flocks of wild ducks on the Reservoirs and on Old River, and flocks of kildees on the Commons; and there were squirrels in the woods, where there was abundant mast for the pigs that ran wild in them, and battened on the nuts under the hickory-trees. There were no other nuts except walnuts, white and black; but there was no end to the small, sweetish acorns, which the boys called chinquepins; they ate them, but I doubt if they liked them, except as boys like anything to eat. In the vast corn-fields stretching everywhere along the river levels there were quails; and rabbits in the sumac thickets and turnip patches. There were places to swim, to fish, to hunt, to skate; if there were no hills for coasting, that was not so much loss, for there was very little snow, and it melted in a day or two after it fell. But besides these natural advantages for boys, there were artificial opportunities which the boys treated as if they had been made for them; grist-mills on the river and canal, cotton-factories and saw-mills on the Hydraulic, iron-founderies by the Commons, breweries on the river-bank, and not too many school-houses. I must not forget the market-house, with its public market twice a week, and its long rows of market-wagons, stretching on either side of High Street in the dim light of the summer dawn or the cold sun of the winter noon.
