 buildings. In such fields, shades should be built, either temporary 

 or permanent in nature. A cheap permanent shade can be built by 

 simply setting posts in the ground to serve as a support to a roof 

 made of boards. In rainy weather, however, a roof of this sort lets

 At somewhat increased cost, this fault can be remedied by covering 

 the boards with roofing paper. A shade similar to the one above 

 can be placed on dimension pieces four by six inches and thus be 

 made movable. Roofing .paper does not necessarily need to be
