Sir George Newnes, Bart, m. p., one of the leading newspaper 

 and periodical publishers in Great Britain, died on June 9 at the 

 age of 59. Sir George was at the head of Newnes Co., Limited, 

 his publishing concern. He has been referred to in The India 

 Rubber World as interested in the Inambari Para-Rubber Estates, 

 Limited, with properties in Peru, in which his sole surviving 

 child, Frank Hillyard Newnes, Bart., is a director. The latter is 

 also a director in Galvez Rubber Estates, Limited, with properties 

 in Bolivia, and in Newne» Co., Limited. 



DYNAMITE ROCK DRILL HOSE. 



"""THE fact that widespread public notice is not taken of the 

 ■*• rubber tube. The better this is protected from wear, from 

 heat, and from other destructive elements, the longer is the life 

 of the hose. The illustration shows a type of hose that is not 

 very strong, but in which the tube is protected with scientific 

 thoroughness. It is covered on the outside by a ply of heavy 

 frictioned duck which, in turn, is covered with a dense tough 

 coating of compounded rubber. This in turn is protected by a

braided covering of non rustable annealed steel wire. Outside 

 of this is wound spirally a protecting jacket of concave non 

 rustable steel wire. The tube is protected on the inside some- 

 what as it is on the outside. First with a ply of heavy duck, 

 then by a coil of special spun steel wire which is bedded in and 

 covered by a layer of rubber. This hose is not only very 

 strong, standing a pressure of over 1,000 pounds to the square 

 inch, but very flexible. [Mulconroy Co., Inc., No. 722 Arch

A NEW AVERAGING INSTRUMENT. 



A XOVEL piece of engineering apparatus is the new Bristol- 

 ■** Durand Radii Averaging Instrument, for circular chart 

 records, of which an illustration appears here. As automatic 

 recording instruments for pressure, temperature, and electricity, 

 using circular charts, have come into such general use, there 

 has developed a demand for a simple device to quickly determine 

 the average of the record made on such charts, and the integral

value for the whole 24 hours, or fur the time covered by the 

 record. The instrument illustrated embodies a wooden base 

 with a metal socket, which is provided for supporting and cen- 

 tering the chart. The socket holds a rotatable pin with a vertical 

 slot at the top to receive the bar which carries the integrating 

 tracer point and triangular support. The vertical groove in the 

 rotatable pin allows the integrating wheel to roll on the chart 

 with uniform pressure due to its own weight. The manufacturers 

 are The Bristol Co., at Waterbury, Connecticut.
