Where it is possible in locating a curb market to select a satis- factory site, insofar as other considerations are concerned, on one of several types of pavement, a smooth hard type such as concrete should be chosen in preference to cobblestone. It is difficult even with repeated flushings to keep rough cobble surface in a sanitary condition. Asphalt pavements are also preferable to cobblestone in the cooler sections of the United States, but in the warmer sections such pavements soften and may be seriously injured by stamping horses. Where only temporary or inexpensive improvements are to be made on special market sites a gravel or cinder surface often will give fair satisfaction. The kinds of structures used for shelter on open public markets in the United States vary from simple sheds, barely wide enough to.

This shed is used on a wholesale market but is better suited to a retail market. cover a single wagon, to broad structures roofing the entire market tract. Very narrow sheds are seldom satisfactory. One of the most popular types of shed is centered over a walk with curbs 8 to 12 inches high the shed having sufficient overhang to protect vehicles on both sides of the walk, backed against the curbs. Such a type of shed, built from structural steel, is shown in figures 2 and 3. Sheds of this type may also be constructed of timber or concrete. The type of structure which may be used in units to cover com- pletely the market tract is shown in figure 4. Of course, such struc- tures are more costly than the simpler types of sheds. The wider sheds are not needed on open retail markets except perhaps those in large cities, but may be very useful for wholesale markets especially where such markets do an important business throughout the Pleas
