Use "water-cart" in a sentence
"A solitary water-cart goes jingling down the wide pavement, and spirts a feeble refreshment over the dusty, thirsty stones."
"Here and there some specially remarkable circumstance, such as a water-cart or a guardsman, fairly penetrates into the seat of thought and calls them, for half a moment, out of themselves; and you may see them, still towed forward sideways by the inexorable nurse as by a sort of destiny, but still staring at the bright object in their wake."
"And then the early water-cart, cleansing the reek of the streets, had approached through the strange-seeming, useless lamp-light; he seemed to hear again its rumble, nearer and nearer, till it passed and slowly died away."
