Since 1904 the customs returns of British guiana have 

 furnished, as a separate item, the exports of rubber from that 

 colony. The figures as furnished by the secretary of the Per- 

 manent Exhibitions Committee, are as follows : 



1904-5 founds 951 1907-8 pounds 6,873 



1905-6 4,114 1908-9 5,751 



1906-7 2,563 1909-10 6,369 



JAVANESE Kapok from the Ceiba pentandra is being used 

 in the arts more and more. The elasticity of the fibre has 

 given it prominence over all other fibre fillers. Besides, it is 

 cleanly, does not absorb moisture readily, and will not rot. In 

 1889 there were exported from the Dutch possessions in the 

 Far East 1.250 tons, in 1910 the business amounted to about

9,000 tons. Recent German success in spinning it may eventu- 

 ate in a fabric that will appeal to the rubber trade, or those who 

 make life preservers and boat cushions may be interested to 

 know that while a cork-filled life preserver will, when sub- 

 merged, support six times its own weight, one stuffed with 

 Kapok will hold up 30 times its weight. These facts are brought 

 to our attention by the Department of Agriculture, Buitenzorg, 

 Java. 



WEARING GOLOSHES IN RUSSIA. 



IT is more than a little difficult [writes somebody in Odessa], to 

 * understand why the average Englishman regards the wearing 

 of rubbers as more or less an effeminate custom. From the 

 hygienic point of view, the Russian attaches a prime importance 

 to warm feet. In this country the wearing of goloshes during 

 the late autumn, winter and early spring is universal among all 

 classes save the peasantry and the rank and file of the army. 

 The rubber is as commonly worn by commissioned officers as it 

 is by civilians. The military rubbers are of special make, with 

 brass heel-bits and sockets for the spur shanks. From the uni- 

 versities down to the primary schools the wearing of rubber 

 overshoes in winter is obligatory. 



The goloshes worn in Russia are all of domestic manufacture. 

 The yearly output is estimated at 45,000,000 pairs, of which a 

 considerable number is exported. Prices during 1910 were 

 increased to nearly double the prices of the preceding year. 



One indication of the progress of the city of Manaos, the 

 rubber capital of the upper .'\mazon, is the existence there of a 

 well equipped telephone service — the Empreza Telephonica de 

 Manaos. The latest directory of this service, printed on one side 

 of a large sheet, contains the names of 330 subscribers, including 

 all the handlers of rubber in Manaos, the public offices, and lead- 

 ing professional men.
