The building of parks along the shore is dictated by considerations of health and enjoyment. The ease with which the work can be accomplished becomes apparent when one considers that the refuse of the city seeks a dump which cannot be found anywhere else than on the Lake front. Probably 1,000,000 cubic yards of waste are annually conveyed to the Lake front from Evanston to South Chicago, enough to fill twenty acres of ground, raising it seven feet above the surface in twenty feet of water. The necessary breakwaters having been built, this constantly growing amount of waste material can be put in place cheaply. Therefore, it is wise to provide now for the disposition of it, and to design beautiful and extensive park strips along the entire shore, which will almost build themselves in the course of another generation. Indeed both health and danger to navigation prohibit the emptying of this spoil in the Lake, as has been done in the past. [Illustration: LIII. CHICAGO. THE MIDWAY PLAISANCE, SHOWING THE PROPOSED WATERWAY CONNECTING THE LAGOONS OF WASHINGTON PARK WITH THOSE OF JACKSON PARK, AND EVENTUALLY WITH THE WATERWAY OF THE PROPOSED SHORE PARK EXTENDING FROM JACKSON PARK TO GRANT PARK. COURTESY OF THE SOUTH PARK COMMUNITY CLUB ] These lagoons, protected from the waves of the open Lake and sheltered from the wind by the city on one side and the park strips on the other, will be a powerful attraction toward open-air athletics, both winter and summer; they will afford a course for races for Northwestern University at the north and the Chicago University at the south. House-boats, launches, canoes, rowboats, and small sailboats will ply upon them, as well as craft for the public use, such as are usual on the Thames, the Seine, and the canals of Venice. The waterway should be lined with restaurants and pleasure pavilions and with public bath houses; swimming beaches should be constructed on their shores, which by careful designing can be made as picturesque as any inland river. Both shores should be a part of the general design, and together with the lagoon itself these shores should be owned by the park authorities, in order that the whole may be effectually policed.
