Describes the characteristics of the boll weevil, the damage that it causes to crops, and methods for its control.

Discusses the life cycle of the webworm, the damage it can cause to cereal and forage crops, and methods to control it.

This report presents a brief history of France's attempts to promulgate an internal air traffic law and then provides a draft of proposed national air traffic laws.

The ways in which the international and internal French air traffic accords interact with each other is outlined in this report. The principal questions covered by the present legislation are as follows: 1) Conditions of safety which must be fulfilled by aircraft; 2) Licenses for members of the crew; 3) Traffic rules to be observed by French and foreign aircraft.

The author attempts to correct the misconception that piloting an airplane requires extraordinary skill and balance. He also tries to show that airplanes are extremely stable in flight. Some of the major points covered in this article include: automatic pilots, airplanes designed to be stable, and the reliance on mathematics to help in designing stable aircraft.

The aerial convention delegates are listed as well as the set of rules that were developed during the session.

This article considers some of the causes which hinder the development of aircraft insurance. Different risks are discussed as well as the causes of aircraft accidents. Pilot error, poor airdromes, weather conditions, poorly adapted airplanes, and engine failures are all examined and some conclusions are made.

This report presents a recounting of the steps taken by France to establish national and international regulation over air traffic.

The technical requirements for commercial aircraft are listed, which include: safety, economy and comfort. The author lists various methods to increase these requirements in commercial aircraft.

The author lists rules for the development and planning of air routes. He uses as examples India and Texas, as well as discussing the need for more landing fields.

Dr. Warner examines the utility and economy of flying at night when flying passengers. Some of the points discussed include lighted landing fields, the possibility of using airships, and the cost of landing fields.

This report examines the great utility and safety of using instruments when flying. Instruments can be especially useful in conditions when the pilot has trouble spatially orienting himself.

This article discusses the need for government subsidies to encourage the development of passenger and freight transport by air.

Here, the purpose is to show that the characteristic performance of a syphon diaphragm can be predicted from a knowledge of its stiffness and of its dimensions. The proof is based on a mathematical analysis of this type of diaphragm, together with enough experimental data to prove the validity of the assumptions and the sufficiency of the analysis. Equations are developed for the performance of syphons under various conditions of loading, both for concentrated loads and for hydrostatic pressure.

The air flow and the air force created by all elements of the propeller blades lying in a ring located between two concentric circles around the propeller axis are independent of what happens in other rings.

The choice of the numbers of revolutions and of the diameter, the distribution of thrust, and the values of the constants in the aerodynamical equations of the propeller are discussed.

Report discussing a new instrument is described which is capable of simultaneously recording the position of the three controls of an airplane. The records are taken photographically on a standard N.A.C.A. film drum and the instrument can be quickly installed in any airplane.

"No rational column formula has yet been developed which gives results which are sufficiently precise for the design of airplane members, and consequently it is necessary to fall back upon experimental testing. In order to derive the maximum benefit from experiments, however, it is necessary that the experiments be guided by theory. It is the object here to modify existing formulae that may be obtained with a minimum number of tests" (p. 1).

Technical paper issued by the Bureau of Mines over shaft sinking safety. Safe mechanical equipment and procedures are discussed. This paper includes illustrations.

Describes various uses for alfalfa, with instructions for each.

Patent for a device to reliably and effectively secure the radiator cap in position on the filling neck of a radiator in order to avoid displacement. Device is of simple and durable construction and inexpensive to manufacture.

Patent for a brake (as it pertains to vehicles), that is operated by hand and that employs the use of brake bands and a drum to alter the momentum of a vehicle.

Patent for hair clippers that simplifies construction, reduces vibration, and improves efficiency.

Monthly literary journal of A. & M. College of Texas containing original short stories, essays, poetry, and other creative works written by students.
