This department will, so far as possible, publish maps and descriptions of various bicycle routes in the vicinity of different important cities in America. The map this week is of New York city. It shows at once just what can be done with a bicycle in New York, what are the best ways of getting out of the city, and where the best streets for wheeling are through its whole length. Most of the black roads are of asphalt pavement, but of course the Riverside Drive, West Seventy-second Street, and the long avenues above the Park, as well as those in the Park, are of macadam. It will pay wheelmen, or boys and girls who expect to be wheelmen or wheelwomen soon, to tear out this page and keep it for reference, for by careful study it will show how to avoid pavement, so far as possible, in getting from one part of the city to another. To begin with the East Side below Fourteenth Street. The wheelman's object must be to get to Second Avenue as directly as possible. He should then go up Second Avenue, which is asphalted to Twenty-second Street, turn east into Lexington, and go up the latter to Thirty-second Street. Here is the beginning of Murray Hill, and the asphalt stops. He has two blocks to ride on Lexington, and then turning west he has half an avenue block uphill to Park Avenue and Thirty-fourth Street. From here he has almost a clear asphalted or macadamized road out of New York. He turns through to Madison Avenue on any street from Thirty-four to Fortieth, goes down the paved hill between Forty-first and Forty-second streets on Madison Avenue, and then keeps on the latter till he turns through Fifty-eighth Street, crosses Fifth Avenue, and if a dry day enters the Park, or if too soon after rain passes west up Fifty-ninth Street.
