Jules Bessonneau THE GERMAN AERIAL FLEET. So much activity has taken place in Germany on the construction of dirigibles, and so many airships have been constructed and. proposed at one time and another in that country, that it is a little difficult to exactly estimate what does and does not exist at the present time. The following table, which has been published by our French contemporary t'Intransegeant, purports to be a correct statement of the present German aerial fleet, based on statistics compiled by an officer of the French Army :— Name.

Smith and W. H. Dorey, Ltd. It is claimed for this valve that although possessing the advantages of a nickel valve, it has not the disadvantages usually associated with the latter type of valve. With valves made of nickel, as no doubt most of our readers know, the stems are somewhat weak and are apt to break without warning. For aeronautical work in particular this is a point of considerable importance, as it would possibly lead to serious consequences. On the other hand, the nickel valve has the one great advantage Diagrammatic sketch show' ing the Smith' Dorey valve in section, the shaded portion being the pure nickel seating. 408 that it requires very little grinding in and cleaning. In the Smith-Dorey valve the seating portion is of pure nickel, whilst the body of the head and the stem are constructed of 3 per cent, nickel steel, thus securing great strength where it is most required. It will be seen, therefore, that by the combination the above-mentioned difficulties are overcome. The makers can supply these valves to manufacturers and others to comply with any special design. It should be mentioned that the nickel seating is set into the valve-head by means of a special patented process, whereby a very tight joint is obtained.
