GREAT BRITAIN. 



At the forthcoming Aero and Motor Boat Exhibition at Olym-

A meeting of the shareholders of Okonite, Limited, was to

The directors of Telegraph Construction and Maintenance Co., 

 Limited, have declared dividends for 1909 amounting to 17J/2 

 per cent. The total for 1908 was 15 per cent. 



Manchester exports classed as india-rubber goods, according 

 to the United States consul, amounted during February last to 

 £6,730 4s. 2d. in value, against £2,682 2s. Sd. for February, 1909. 

 The balata and other belting included was of the declared value 

 of ii,3/6 4s. 2d., against nothing in February, 1909. 



The directors of the Stepney Spare Wheel, Limited, have de- 

 clared an interim dividend at the rate of 20 per cent, per annum

LARGE DREDGING HOSE. 



THE "KICKOFF." 



"yilE illustration relates to the "Kickoff," first used by the 

 *■ Hood Rubber Co. (Boston), on their "Mood brand" self- 

 acting shoes instead of the spur. It proved, however such a 



success during the past season that the c mpany are now- using 

 it on all their "Hood brand" styles, with a few exceptions. The 

 Kickoff is referred to as preventing a short fit, and giving 

 extra service just where it is needed. 



YV71IAT ' s sa ''' t0 Dc ln> largest piece of rubber hose yet 

 *• manufactured is illustrated on this page. Its inside diam- 

 eter is 29 inches; outside diameter. 3^ inches. The hard service 

 demanded of dredging hose is due to the fact that the sand 

 and mud of the rivers and harbors naturally gravitate toward 

 the lower places, particularly the channels, which require dredg- 

 ing at frequent intervals. When, as is generally the case, this 

 movement is assisted by tidal action, the channels soon become 

 too shallow for large vessels, and the giant steam suction dredge 

 is then employed as the most economical means of restoring 

 depth. 



The centrifugal pumps in one of these dredgers must be equal 

 to removing a 40 per cent, solution of sand and water, which, 

 by the use of a pipe line, may be deposited on near-by marshes, 

 reclaiming them for commercial use, and making up at least 

 a part of the large expense involved in dredging. These pipe 

 lines are made up of lengths of iron piping, mounted on pontoons, 

 the lengths being connected by rubber tubing, the flexibility of

which permits the rise and fall of the sections made necessary 

 by the tides. Of greatest importance, though, is the suction hose 

 with which such a dredge must lie equipped. 



The hose here described was made as follows : A cold rolled 

 steel red an inch in diameter was formed into a spiral coil. 

 Sheet rubber was then applied by hand so as to encase this coil 

 and its interstices, it being intended that any slight imperfection 

 in one layer would be offset by the next layer applied. This 

 formed a tube or lining, such as would best withstand the action 

 of the sand and other material which, being drawn rapidly 

 through by thousands of tons, would otherwise soon destroy the 

 hose by abrasure or cutting. 



The completion of the hose resulted from the application of 

 alternate layers of specially constructed duck and rubber, until 

 the requisite strength had been obtained. A cover of gum was 

 then put on to protect the hose from the action of the water 

 from the outside, which otherwise would in time produce dis- 

 integration. The whole section was then vulcanized. This hose 

 was made by the Combination Rubber Manufacturing Co., at 

 Bloomfield, New Jersey, who, it is understood, have received 

 orders for more hose of the same kind. 



The yield of the Mabira Forest 1 Uganda) Rubber Co., Limited, 

 who are collecting Funtumia rubber, was reported for the nine 

 months ending September 30, 1909, at 161,864 pints of latex, 

 which averaged one pound of dry rubber to 2^2 pints of latex. 

 Atmospheric conditions and other conditions are stated to have 

 slightly affected the number of pints necessary for one pint of 

 rubber. The weight .it' rubber indicated is 64,746 pounds.
