tion of one or two items might be of some assistance. The sulphur box 

 is made with sloping ends and is used for mixing water with the sul- 

 phur. A liose could be used to supply the water, but it is economy to 

 put up a hydrant, as shown. A hydrant is also placed at the other 

 corner near the barrels, and a short hose is attached for filling the 

 barrels, and to extinguish any fires that may start in the sulphur. The 

 strainer platform shown in the top view (Fig. 109), is used to pull the 

 strainer out, so it may be cleaned. 



The following is a list of materials used in building the platform : 



20 pieces 2 x 6 x 10 Oregon pine, Merch. — Floor and stairs. 



3 pieces 4 x 4 x 12 Oregon pine, Merch. — Beams under floor. 



6 pieces 4 x 4 x 14 Oregon pine, Merch. — Twelve posts. 



20 pieces 1 x 4 x 10 Oregon pine, Merch. — Braces. 



1 piece 1x10x10 Oregon pine, Merch. — Sulphur box. 



1 piece 1 X 12 X 5 Oregon pine, Merch.— Sulpliur box. 



1 piece 1 X 10 X 15 Oregon pine, Merch. — Sulphur box. 



1 piece 2 X 18 X 12 redwood, Clear — Strainer box. 



The planks for the floor are put two inches apart so that water and 

 waste materials will not collect on the platform. At the retail market 

 price the above lumber amounts to $11.83, but in our own ease was cut 

 to practically nothing by the use of old lumber and left-overs from 

 other buildings. 



THE COOKING BARRELS. 



A good wooden barrel of fifty gallons capacity is used for this pur- 

 pose. A hole 1| inches in diameter is cut in the center of the bottom 

 of each barrel so that the finished material can be run quickly into the 

 strainer below. The hole should be slightly beveled, as shown, so that 

 the wooden plug will fit tightly and prevent leakage when closed. The 

 valve is controlled by means of the f-ineh iron rod, which runs through 

 the plug and is held to it by the two lock-nuts, which is in itself held in 

 place by means of the f-inch iron pipe. The rod slides up and down 

 through the pipe, thus opening and closing the valve. The pipe is 

 screwed into the iron brace, which is bolted to the bottom of the barrel, 

 and to the wooden brace, which is nailed across the top. This holds the 

 pipe fast and always insures the return of the plug to the opening. A 

 hollow square wooden trough about six inches long is nailed to the 

 bottom of the barrel (Figs. 109 and 110), to prevent the liquid from 

 splashing or running out on the floor of the platform. 



The steam is led into the barrel through the steam pipe (top view. 

 Fig. 110) and controlled by the Jenkins disc valve. The loop inside 

 the barrel (Fig. 110) has sixteen g^-incli holes, drilled in the positions 

 shown in the plate, for distributing the steam evenly. This loop lies 

 as close to the bottom of the barrel as possible (about 1^ inches, depend- 

 ing on the hoops) and the hole through which it enters is tightly corked. 

 The fittings and their positions are given in the drawing, so it is 

 unnecessary to give further details, except to give a list of steam and 

 water connections for quick reference.
