THE INDIA RUBBER WORLD 



207 



hibition recently issued by the government, which must be re- 

 garded as a retaliation for the English declaration of rubber as 

 contraband. The step has been taken in the interest of the perm- 

 anent readiness of the army, and is intelligible, as with the pres- 

 ent supplies of crude rubber, although of themselves not unim- 

 portant, which were increased by large quantities from Antwerp, 

 economy must be observed. Of late, all rubber with dealers and 

 manufacturers has been attached, with the liberty to use it only 

 for the necessary requirements, which are indicated in detail. 

 The number of workers must, therefore, now be restricted, and 

 we would be inclined to believe that the average production of 

 the factories will nol exceed one-third of that in times ,,f ; 



"We have also been obliged to limit our operations. The work- 

 men taken for the army, about "in- fifth of our staff, have not 

 been replaced, and the working time has been reduced to about 

 four days a week. With any restriction, the workmen alwaj 

 earn enough to be able to live without anxiety. I'nder these cir- 

 cumstances, the rubber in the country will suffice for a very long 

 time. 



"Sufficient provision has been made for the families of the 

 workmen drafted to the field, by the factory management and the 

 state funds. Moreover, state and municipalities provide re- 

 munerative occupation for all the unemployed, on public build- 

 ings, railways, highway and canal works; and the expenditure of 

 large sums is projected to support the industries most affected by 

 stock orders for the public departments. It is distinctly stipulated 

 that the necessity will not be utilized for the reduction of wages.' -

 the largest rubber culture associations.

 Intermediate Cultures"; Heer C. M. Hamaker, on "Planting Dis-

SEALING MACHINE WITH RUBBER ROLLERS. 



Where there is a single envelope to be sealed it is not a matter 

 of vital importance as to how it is done— the time-honored meth- 

 od of using the tongue is quite satisfactory, if that method is to 

 one's taste. But where there are a thousand envelopes to be 

 scaled some other method must be pursued. Various sealing 

 devices have been put on the market, some good and some not 



so good. Hen is ne that 

 works by electricity, and it 

 is mentioned here because 

 an important 

 part of its con- 

 struction con- 

 sists : five 

 rubber rollers. 

 Twr, of them 

 are shown in 

 the accompany- 

 ing illustration, 

 at the top of the machine, just back of the large wheel. The 

 envelope is first placed between a rubber roller and a wheel with 

 a moistened edge which wets the mucilage on the flap. The en- 

 velope is then carried on between two pairs of rubber rollers, 

 which effectually seal it. Both machine and tray are equipped 

 with rubber feet so as not to scratch the desk or table. [Sealo-
