Equipped with Junior Pump. This pump is intended to boost the pressure of the chemical tank and can also be used as an auxiliary pump. On this type of steamer the pump will deliver 250 gallons of water at 120 pounds pump pressure. _Courtesy of American LaFrance Fire Engine Co._] [Illustration: COMBINATION CHEMICAL ENGINE AND HOSE CAR Equipped with hose reel instead of hose basket as in other types illustrated. _Courtesy of American LaFrance Fire Engine Co._] [Illustration: THE BODY OF THIS CAR HAS A CAPACITY OF 800 FEET OF 2-1/2-INCH FIRE HOSE AND IS ALSO EQUIPPED WITH A 40-GALLON TANK, WITH CHEMICAL HOSE, FIRE EXTINGUISHER AND EXTENSION LADDER.[51]] [Illustration: GASOLINE TWO-WHEEL FRONT-DRIVE AERIAL TRUCK[51] One hundred horse-power; six-cylinder motor; speed, 25 miles per hour; locomotive bell and hand-operated siren horn; extinguishers, two 3-gallon Babcock, fire department standard; lanterns, four, fire department standard; axes, four, fire department standard; wall picks, two; crowbars, two; shovels, two; wire cutter, one; door opener, one; tin roof cutter, one; pitchforks, two; battering ram, one; Manila rope, tackle and snatch block; pull-down hook with pole, chain and rope; rubber buckets, four; crotch poles, two; pike poles, six, assorted lengths; wire basket, one under frame; one 10-inch electric searchlight.] [Illustration: GASOLINE TWO-WHEEL BEVEL-GEAR FRONT-DRIVE WATER TOWER[51] One hundred horse-power; six-cylinder motor; speed, 25 miles per hour; one 10-inch electric searchlight; locomotive bell and hand-operated siren horn; deck turret, one, mounted; nozzle tips, three for deck turret, 1-1/2-inch, 1-3/4-inch, 2-inch; three for tower nozzle, 1-1/2-inch, 1-3/4-inch, 2-inch; hose, one 35-foot length, 4-inch cotton, rubber lined; lanterns, two, fire department standard; axes, two heavy pick back, fire department standard; crowbar, one of steel, held by snaps.] The Story of the Taking of Food From the Air[52] What is the greatest discovery of the last twenty-five years? Probably you will say the wireless telegraph, the flying machine, moving pictures or the phonograph, but it would be none of these, according to the _Scientific American_. This publication discussed at great length the subject of what invention of the last twenty-five years was of greatest value to mankind. First place was given not to the wonderful inventions that are so large in the public eye, but to the fixation of nitrogen from the air for fertilizer purposes. Why? Simply because this discovery stands between man and starvation. Other inventions are vastly important, but this one is vital. Looking at it from the broadest view there can be no other decision. The time is here when to feed the world is becoming a more and more difficult problem.
