In 1820 Dr. James Lovell, Surgeon General of the Army, suggested to General Thayer, Superintendent of the Military Academy at West Point, that Cutbush be appointed Chief Medical Officer at the Academy and Post of West Point. In this capacity he served for seventeen months, when he became Acting Professor of Chemistry and Mineralogy in the Academy. The first lecture in his new position was delivered October 9, 1820. In a sense, it marked the beginning of a new career for Cutbush. He resumed teaching duties, but gave himself more particularly to the study, not only of gunpowder, which never ceased to be interesting to him, but to explosives of higher character, and in this latter field he reached his greatest eminence and may confidently be regarded as a pioneer in it. Just before leaving Philadelphia, in the year 1820, Cutbush wrote Benjamin Silliman at some length on an improvement of the Voltaic electrical lamp. It was an ingenious modification and constituted the first contribution made by Cutbush to the _American Journal of Science_. But, returning to his life at West Point, it may be observed that in 1822 he contributed his second article to the _Journal of Science_, which did not appear in print, however, until 1824. This article related to the composition and properties of the Chinese fire and the so-called brilliant fires. It was very interesting. It displayed a thorough and wide knowledge of pyrotechnics with which Cutbush, in previous years, had been gradually familiarizing himself. At one point he said: "Most if not all the compositions used in fireworks, including military fireworks, were more the result of the labours of the artisan who was neither controlled by fixed principles nor by a knowledge of the effects and properties of bodies and of the systematic experiments of the chemist, and yet in consequence of some fortuitous and repeated trials we find that he has been successful, and moreover has amassed a body of facts which we may reasonably infer may either be rendered more perfect by knowledge or improved upon by the exact aid of chemical science." Here is every proof of his purpose to apply his understanding of chemical principles and his own experience to the solution of pyrotechnic problems, for he continues: "Pyrotechnics is at present considered under two heads, namely, fireworks for exhibition and military fireworks. The latter is undoubtedly the most useful, as it embraces a variety of propositions calculated for attack and defence both for naval and land service." Almost simultaneously there appeared in the same _Journal of Arts and Science_ another contribution by Cutbush, entitled REMARKS CONCERNING THE COMPOSITION AND PROPERTIES OF THE GREEK FIRE
