SUGGESTIONS AS TO LABOR REQUIRED. 



Excavations. Excavate for the vat, as shown by the drawings, to the proper depth; 

 level the bottom of the pit for the sills of the vat. After the vat is completed and 

 the outside has been coated with coal tar, fill in around the vat, using the surplus 

 earth to grade the sides of the vat a little above the natural grade, sloping slightly 

 from the vat. Dig all holes required for the gate and fence posts.
