tion, which gives greater strength and simplifies the 

 matter of securing water-tight joints. The sides are of 

 pine, two inches thick, ten inches wide, and six feet 

 long. The lower angles are rounded off, as shown in the 

 engraving. Four inches from each end grooves are cut 

 half an inch deep and two inches wide. Into these are 

 fitted and nailed two pieces of pine, two Jby eight inches, 

 and twenty-five inches long. They are flush with the 

 top, leaving a space of two inches at the bottom. Two 

 rods of half-inch round iron, each with a head at one 

 end and a screw-thread and bolt at the other, are in- 

 serted through holes made for the purpose, near the top

of the cross-pieces and screwed firmly in place. The 

 bottom is of galvanized iron, seven feet eight inches long 

 and twenty-eight inches wide. This is fastened by a 

 double row of three-penny nails to the lower edge of the 

 side pieces, extending around the curves to the top. If 

 desired, it may be cut long enough to turn over at the 

 top, and nailed to the upper edge of the wooden cross- 

 pieces. This would give sufficient strength without the 

 iron brace-rods. This vat is set upon an arch of brick or 

 stone two feet wide, so that the wooden sides will project 

 over it. For scalding hogs, a scraping bench is erected 

 close to one side of the vat, and level with the top.
