Selected Bibliography of Engineering Subjects.--The Engineers' Council for Professional Development has recently published a list of books of college grade, chosen through consultation with a large group of experienced engineers and educators as worthy examples of the best in professional literature. It should be helpful in providing guidance to young engineers who wish to extend .their academic training by further study either in familiar fields or in new ones. R. H. O. Fellowships for Advanced Study.--In order to improve the quality of education and the practice of the arts and professions in the United States, to foster research, and to provide for the cause of better international understanding, the John Simon Guggenheim Memorial Foundation offers a limited number of Fellowships, tenable under the freest possible conditions, for research in any field of knowledge and for creative work in any of the fine arts, including music. In the main, the Fellowships have been granted for work abroad; but for I938-39, in exceptional cases, a limited number may be granted for work in the United States. R. H. O. Forest Fire Fighters Get Supplies in Parachutes.--The United States Department of Agriculture states that emergency parachutes made from pieces of burlap about six feet square have been used successfully by the Forest Service to drop food and other supplies from airplanes for men on remote fire fighting lines in the national forests. Large burlap sacks, used in bagging wool, generally are used to make the parachute. In one experiment nine dozen eggs were dropped 5oo feet in one of the homemade parachutes and only two eggs were broken. Food in glass jars, canned milk, w a t e r , and even tools, have been dropped to aid the fighters. Such delivery saves much needed time in emergencies. R. H. O.
