Officer McWatters, whose urbanity and politeness is proverbial, was accosted yesterday forenoon, by a young man who had just stepped off of the Fall River boat, who inquired of him to know the way to the Park. "What park?" politely queried the officer. "O, I don't know,--any park where I can sit down a while, and see something of New York!" "Better take a stage and go to Union Park. Everything clean, quiet, and orderly." The officer assisted the young man into the stage, which soon sat him down in Union Park. The Park never looked lovelier. Children and drums, nurses and baby-wagons, small boys and fire-crackers, lovely maidens with books of poesy, the water-basin and the flowing fountain, the green trees and the luxuriant shade, all were but parts of a perfect whole, which Mr. Jasper Gray, the young man in question, enjoyed hugely. Mr. Gray is a native of that enterprising village known as Fall River, and he had come to New York to see the sights. The senior Gray had warned him to look out for the "sharks;" and with a promise that he would do so, and about one hundred and sixty dollars in his pocket, the young man left his home, to sojourn several weeks in and about the Metropolis. Mr. Gray's idea of "sharks" was, that of some huge braggadocio, who would fiercely assault him late at night, demand his money or his life, or assume some other equally disagreeable mode of placing him in a dilemma. He had no idea that under the bright sun of midday, and in the grateful shade of the trees of a public square, the shark was looking and watching for a victim; but so it was. As he cast his eye towards the fountain, his gaze rested upon a little child playing on the greensward, now rolling on the grass, and again approaching dangerously near the water's edge. Once thinking that the child might fall in, he sprang from his seat, and caught the little fellow by the arm, and delivered him into the hands of his nurse. A few moments after this occurrence an elegantly-dressed young lady came up to the seat upon which he was sitting, and begged leave to thank him for having so kindly cared for her little brother, whom, she declared, he had saved from falling into the water. "Nurse has gone home with the darling, now; but I could not feel to leave you without expressing my gratitude for your kindness," said the lady, whose eyes shone with brilliancy through the thin gauze veil, filling Mr. Jasper Gray with the most undefinable feelings.
