Du Pont farmer's handbook; instructions in the use of dynamite for clearing land, planting and cultivating trees, drainage, ditching and subsoiling . COIL OF LEADING WIRE Thawing Kettles are made in two different styles. The Brad-ford Thawing Kettle has two separate pails, the one for the dyna-mite fitting tightly into the one for the water. It is made in two sizes,the No. 1 size holdmg 22 pounds and the No. 2 size 60 pounds ofdynamite. The Catasauqua Thawing Kettle is made in one piecewith an outside jacket for the hot water all around the dynamite sec-tion. The No. 1 size holds 30 pounds of dynamite and the size 60 pounds. The water must never be heated in the Catasauqua Kettle, butmust be heated m some other vessel, and when not too hot to burn thehand, poured into the water compartment provided the dynamitecompartment is empty. It is dangerous to heat the water in theCatasauqua Kettle even when the dynamite section is empty, becausethere may be a little nitro-glycerin in it which has soaked out of thedynamite previously thawed. Water may be heated in the outerpail of the Bradford Kettle if the inner pail has been removed.
