usually put in the head? Are all rockets furnished with a head? What is understood by the furniture of a rocket? How are the serpents, stars, fire-rain, etc., forming the furniture of a rocket, discharged into the air, when the rocket has terminated its flight, or arrived at its maximum of ascension? What forms the difference between a balloon, in fireworks, and a rocket? As the balloon contains also furniture, and is projected vertically from a mortar, how is fire communicated to it, so as to burst it in the air? Is the fuse used, in this case, the same as that for bombs, howitzers, and grenades? What is the Asiatic rocket? The fougette of the French? In what siege were they employed with success by the native troops of India? What was the nature of their war-rocket? What is the murdering rocket of the French? Is the conical head hollow, solid, blunt, or pointed? Why is it called the murdering rocket? What is the Congreve rocket? Is Congreve the inventor or improver of this rocket? What are Congreve rockets loaded or armed with? In what part is the load placed? Is the case made up of paper or sheet-iron? What are the sizes of Congreve rockets?" In the introduction to "Pyrotechnics" Cutbush remarked that he had consulted many authorities without much advantage, finding the French the most helpful. Of the English he said: "As respects the turtle torpedo and catamarin submarine machines, it appears that Bushnel claims the originality of the discovery from the date of his invention, although similar contrivances had long ago been suggested. Fulton's improvements, in the torpedo, are deserving of particular attention, but it is plain that the Catamarin of the English is the same in principle and application as Fulton's torpedo and that Fulton deserves the merit of it." The "System of Pyrotechny" bears the ear-marks of much careful experimental study. It is a most worthy contribution, and is strong proof of the dominating force in the mind of Cutbush, namely, to make his science as widely useful as possible. Chemists may justly take pride in this early contribution in the application of chemical principles. The life story of Cutbush has now been told. It is really the story of his life activities, for regrettable as it is, there does lack a picture of the man's personality. The parents of James Cutbush were Edward Cutbush and Anne Marriat. The father was a stone-cutter or carver. To these good people were given four children: Edward, born in 1772; Ann, in 1782 (who died in 1798); William, born in 1785, and James in 1788. Edward became prominent as a naval surgeon, while William graduated from West Point in 1812, and attained eminence as an engineer.
