On the third day I was genuinely ill and had no wish to do business. Within ten days, however, I was out again, attending to my affairs.
HELL SWAZEY BREAKS UP THE DANCE
About the first use of nitroglycerin in the United States as a blasting agent on a large scale was in the construction of the Hoosac Tunnel in Massachusetts, on the Boston and Albany Railroad.
So many accidents had occurred where the use of nitroglycerin had been attempted, that engineers and contractors were afraid to employ it. Nobel, however, had discovered that when nitroglycerin was absorbed in infusorial earth, it was rendered much less sensitive. This material he called dynamite.
A chemist by the name of Professor Mowbray believed that the main trouble with nitroglycerin had been that it was not sufficiently purified in its manufacture. He induced the builders of the Hoosac Tunnel to try his product. He built a laboratory on the side of Hoosac Mountain, over the village of North Adams, where he produced the stuff.
He put it up in tin cans, which held about a quart. For transportation these were carefully packed with cotton flannel between them.
The method of using the dynamite was to pour it into holes drilled in the rock, inserting an exploder cap and fuze in the usual manner. At that time it was popularly supposed that if nitroglycerin or dynamite were allowed to freeze, it became very highly sensitive and would explode on the slightest jar. Stories were prevalent that the sound of a fiddle string would explode nitroglycerin when frozen.
One day there came an urgent call from the east end of the Tunnel for more nitroglycerin. Professor Mowbray had in his employ a care-free and fear-free fellow by the name of Helton Swazey. When Swazey was sober, he was the soul of good nature, but when drunk, which was very frequently, he was as savage as a hungry cougar. This peculiarity earned Helton Swazey the nickname of Hell Swazey.
