Two pieces one inch by eleven and one-half inches by six feet

(As in the preceding case, the two pieces four and one-half feet 

 long and the two pieces six feet long have an extra foot in length 

 at each end to serve as handles). 



For a four-bag batch (these figures can be obtained by 

 doubling the cubic contents of the boxes, as shown above). 



Shovels: No. 3, square point. 



Wheelbarrows: At least two are necessary for quick work, 

 and those with a sheet-iron body are to be preferred. 



Garden rake.

Tamper : Four inches by four inches by two feet six inches, 

 mth handles nailed to it.

DETERMINATION OF QUANTITIES 



(U. S. Department of Agriculture) 



Quantities of JMaterials and the Resulting Amount of Concrete for a 

 Two-bag Batch 



The number of cubic feet of concrete that will be required for 

 the work in question should first be calculated. By multiplying 

 this number by the number under the proper column, as shown 

 in Table II below, the amount of cement, sand, and stone or 

 gravel can be found.
