Though but a country town with great elm-trees still shading its main thoroughfare,[30] Brooklyn was growing, and its trade was brisk. It is likely that the carpenter, Whitman, framed more than one of the hundred and fifty houses which were added to it during the year. In the meantime, Walt took advantage of his improved situation to study men and manners in a sea-port town. He watched the ferry-boats that for the last ninety years had plied to and fro, binding Brooklyn to its big neighbour opposite upon Manhattan Island. For another sixty years their decks provided the only roadway across the East River, and they still go back and forward loaded heavily, in spite of the two huge but graceful bridges which now span the grey waters. The boy gazed wondering at the patient horse in the round house on deck, which, turning like a mule at a wheel-pump, provided the propelling power for the ferry-boat till Fulton replaced him by steam. The boy in frocks must have wondered, too, at the great shows and pageants of 1824 and 1825 which filled New York with holiday-making crowds. For in August of the former year, came the old hero of two Republics, General Lafayette, to be received with every demonstration of admiring gratitude by the people of America. Some scintilla of the glory of those days--pale reflection, as it was, of the far-away tragic radiance that lighted up the world at the awakening of Justice and of Liberty on both sides of the sea--fell upon the child. For when the old soldier visited Brooklyn to lay the corner-stone of a library there, he found the youngster in harm's way and lifted him, with a hearty kiss, on to a coign of vantage.[31] Thus, at six years old, Walt felt himself already famous. Again, a few months later, the city was all ablaze with lights and colour and congratulations on the opening of the Erie Canal, which connected New York with Ohio and promised to break the monopoly of Western commerce held hitherto by the queen city of the Mississippi. * * * * * By this time, the family counted four children; two brothers, Jesse and Walt, and two little girls, Mary and Hannah, all born within six years. Of the children, Walt and Hannah appear to have been special friends, but we have little record of this period. As they grew old enough, they attended the Brooklyn public school and went duly to Sunday school as well.[32] In the summers they spent many a long holiday in the fields and lanes about West Hills.
