A ROYAL APPLICANT FOR A PATENT. 



pRINCE HENRY of Prussia, whose interest in automo- 

 ■^ biling is a matter of common knowledge, is referred to 

 as a recent applicant for a patent on a device to keep mud 

 and moisture from obstructing the view through glass wind 

 shields. The apparatus is simple, consisting of two arms 

 equipped with rubber edges. The arms are fastened on pivots 

 on either side of the wind shield. A handle is located within 

 convenient reach of the driver, and by turning this handle 

 the rubber edges are moved over the glass, somewhat in the 

 manner that window washers employ when using a similar 

 device on large store windows.

ITALIAN IMPORTS. 



The imports of rubber goods into Italy in 1906, according to 

 the United States consul at Milan, amounted in value to $2,- 

 192,538, against $1,707,066 in 1905. During the first 11 months 

 of 1907 such imports amounted to $2,640,421, not including 

 126,000 pairs of rubber footwear of the value of $132,533. The 

 bulk of the footwear came from the United States and Germany, 

 each country exporting about the same quantity. The consul 

 reports that the manufacture of rubber shoes has lately been 

 established at Milan. 



TARIFFS AND COMMERCIAL TREATIES. 



The new Venezuelan customs tariff, promulgated on Janu- 

 ary 13, 1908, enumerates a number of items of rubber goods. 

 The items chargeable at 75 centimes per kilogram [=$6.56 

 per 100 pounds] for rubber hose and belting and rubber tired 

 wheels. For the following goods the rate is 2.50 bolivars per 

 kilogram [=: $21.87 per loo pounds]: Rubber girdles, shoe 

 elastics, galoshes, and rubber goods generally. The rate on 

 elastic webbing, whatever the character of the fabric involved, 

 is 5 bolivars per kilogram [= $43.74 per 100 pounds]. 



A new commercial treaty between Canada and France pro- 

 vides for the admission into the latter country, or into any 

 of its colonies, of certain Canadian products under the minimum 

 French tariff. The articles listed comprise all manufactures 

 of india-rubber. 



HISTORY OF GOLF BALL MARKING. 



p OBERT SIMPSON, a Western golf champion, tells the 

 * *• Omaha Ji]or!d-Hcrald how golf balls came to have 

 marked surfaces, instead of being perfectly smooth, as when 

 the balls were first made of gutta-percha. Then, he says, 

 it was impossible to make a perfectly straight shot. The 

 caddies on St. .'\ndrews and Carnoustie links, Scotland, where 

 Simpson learned the game, began to bat the balls around, 

 of course, and in a short time they became considerably 

 maimed and chopped up. The caddies .soon discovered that 

 these old balls, cast of? by the aristocrats and experts, after 

 having been sufficiently abused, would carry farther and truer 

 than the new ones. 



This fact became known to the professionals, who began 

 to deliberately hack the balls with chisels and hatchets before 

 using them, with good results. Soon afterward the manu- 

 facturers recognized the importance of this idea and began 

 to mold balls with the corrugations. Hence the present day 

 article, which has been driven 300 yards on the course. 



Several specimens of rubber from the climbing plant Crypto- 

 segia graiidiflora, sent from India to the Imperial Institute, in 

 London, for examination, were reported to exhibit very fair 

 elasticity and tenacity. This plant is reported to be very abundant, 

 especially in the presidentcy of Bombay.
