Temperatures in Spark Plugs Having Steel and Brass Shells
"Brass has often been assumed superior to steel for spark plug shells because of its greater heat conductivity. The measurements described in this report prove the contrary, showing that the interior of a spark plug having a brass shell is from 50 degrees to 150 degrees c. (90 degrees to 270 degrees f.) hotter than that of a similar steel plug. It is to be concluded that steel is to be preferred to brass for spark plug shells. This report embodies the results of measurements taken of electrodes and a comparison of brass and steel insulators of spark plugs while they were in actual operation" (p. 5).

War Gas Investigations: Advance Chapter from Bulletin 178, War Work of the Bureau of Mines
From General Statement: "Beginning with an investigation to develop the best type of gas mask, the scope of the work extended until it included researches relating to a wide range of devices, such as different types of poisonous and irritating gases and smokes, smoke screens, gas shells and gas bombs, signal lights, and incendiary bombs. When the results obtained through this research were to be applied by the War Department, the Director of the Bureau of Mines cooperated in the selection of men to have charge of manufacture or further development, recommending chemists who subsequently received commissions in the Army. Perhaps the greatest result of the research work has been the demonstration of the value of the services that the chemist and chemical engineer can render in time of need and the recognition of chemical investigations as a necessary function of the Government."

"White Ants" As Pests in the United States and Methods of Preventing Their Damage
"Damage by white ants is serious to many classes of crude and finished forest products. These insects are especially injurious to foundation timbers and woodwork of buildings and to material stored therein. Damage to timber in contact with the ground is especially serious in the South. The woodwork of buildings can be protected from the attack of white ants by proper construction and these insects can be eliminated where already established." -- p. 2. This bulletin discusses the life cycle of these insects (also known as termites), the type of damage they cause, and methods for protecting wood and timbers.

The Woolly White Fly in Florida Citrus Groves
"The rapid spread of the woolly white fly over a greater portion of the citrus-producing sections of Florida has caused some alarm among the owners of orange groves. This bulletin contains information regarding the introduction of the woolly white fly into the United States and its subsequent spread. It shows the grower how to distinguish this pest from all other white flies attacking citrus in Florida, gives a general outline of its life history, tells something about its natural enemies, which usually control it, and describes the remedial measures to be applied in case the natural enemies do not seem to promise aid in the near future." -- p. 2
