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. TThere 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

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 year.
