✦ Synopsis
Spread of Gypsy Moth by the Wind. ANON. (Sci. Amer., cx, No. Io, I95.)---Experiments conducted by the U. S. Bureau of Entomology prove that the newly-hatched caterpillars of the gypsy moth may be blown, under favorable conditions, a distance of six miles or more. Thus the wind is an important factor in the spread of this destructive pest.
Wireless Telephony from Berlin to Vienna. ANON. (SCi. Amer., cx, No. Ii, 227.)--Wireless telephony continues to occupy experimenters in various parts of Europe, and, although we have no very remarkable progress to report within a recent date we can mention some promising experiments which are being conducted between Germany and Austria. The Nauen wireless station, owing to its high mast, is favorable to long-distance working, and telephoning was effected from this plant to the Technical Museum at Vienna, a distance over 3o0 miles. Owing to special apparatus of a new design, it was possible to hear newspaper articles which were read at Nauen.
