William Weight & Co. report [July il : 



Fine Para. — In the absence of any general trade demand, prices have 

 been subject to violent fluctuations; hard fine dropped within a week from 

 las. to 9s., and within ten days reacted to io.f. 6d., since declined to 

 10s. id. [ = $2.45]. America has held severely aloof for the near posi- 

 tions, but has bought fair quantities October-December up to as. lid. We 

 would point out that shipments from June, 1909, to _ May 31, 1910, to 

 America from Brazil and Liverpool (allowing for reshipments here) have 

 been 3.400 tons less than the corresponding period last season. Brazil 

 news is firm, and the bulk of the stock which was held back has been dis- 

 posed of. Market closes steady. Value: hard fine July-August 105. id..

A NEW WATERPROOF COMPOUND. 



D l 'HI'. PROLINE is a term applied to a new compound for 

 ■*• *■ various waterproofiing purposes, which is described as im- 

 pervious to gas and acids, with the further advantage that it is 

 flexible. The ingredients in addition to india-rubber are not 

 mentioned, but the effect of their combination is mentioned as 

 forming a liquid rubber of any consistency desired. Uses men- 

 tioned for it are in waterproofing paper bags for transporting 

 various commodities ; for lining paper for barrels and boxes, 

 particularly for shipments over sea; gas tubing, insulation of 

 electrical wires; painting structural iron work; for steam and 

 water packings ; lining fire hose, and so on. For the purpose of 

 marketing this material the Rubberoline Manufacturing Co. (Gar- 

 field, New Jersey) has been organized.
