| Instructions for use. (a) FOR STUFFING BOXES. If the-packing is Flax, Hemp, or Spun-Yarn, the paste to be well rubbed into the fibres, which are then to be pleated, and coated with the paste, the Gland to be packed and as much Glandoline put into the stuffing box as possible. The foregoing applies also to all other packings, but as the latter are already made up, they are only to be well coated with the Paste, and the glands of Steam Engines, Steam Hammers, Pumps, etc., packed therewith. (b) FOR PISTON RODS. A coating of the paste to be put on the Piston Rod and round the mouth of the gland, every now and then on starting the Engine, according to the size and work required of same. ONLY GENUINE IF STAMPED WITH OUR REGISTERED TRADE MARK "GLANDOLINE." STEAM. A cubic inch of water evaporated under ordinary atmospheric pressure is converted into 1 cubic foot of steam (approximately). Steam at atmospheric pressure flows into a Vacuum at the rate of about 1,550 feet per second, and into the Atmosphere at the rate of 650 feet per second. The specific gravity of steam (at atmospheric pressure) is ·411 that of air at 34° Fahrenheit, and ·0006 that of water at the same temperature. 27,222 cubic feet of steam, at atmospheric pressure, weigh 1 pound; 13,817 cubic feet of air weigh 1 pound. Boilers require for each nominal horse power about 1 cubit foot of feed water per hour. Locomotives average a consumption of 3,000 gallons of water per 100 miles run. The best designed boilers, well set, with good draft and skilful firing, will evaporate from 7 to 10 lbs. of water per pound of best quality coal. The average result is from 25 to 60 per cent. below this. In calculating horse power of tubular or flue boilers, consider 15 square feet of heating surface equivalent to one nominal horse power. One square foot of grate will consume on an average 12 lbs. of coal per hour. Steam engines, in economy, vary from 20 to 60 lbs. of feed water and from 1½ to 7 lbs. of coal per hour per indicated horse power. Condensing engines require from 20 to 30 gallons of water to condense the steam represented by every gallon of water evaporated — approximately say from 1 to 1½ gallons per minute per indicated horse power.
