ONE of the most attractive and interesting features of the 

 Second International Rubber and Allied Trades Exhibi- 

 tion which will open in London on June 24, promises to be the 

 various competitions for which handsome prizes in the shape 

 of silver cups, trophies, etc., have been offered. Several of these 

 have already been described and illustrated in the columns of 

 The Indi.\ Rubber World and we are enabled to present here- 

 with an illustration of "The President's Trophy," offered by the 

 president of the e.xhibition, Sir Henry A- Blake, g.c.m.g., for the 

 exhibit proving of greatest interest in connection with the pro- 

 duction, preparation or use of rubber in any form. 



A better idea of the broad scope of this competition may be 

 obtained from the following details in regard to the plan on 

 which the award will be made by competent judges who will 

 inspect and test all exhibits they may consider worthy and make 

 the award according to their own judgment, no matter from 

 what country the exhibit may come. 



1. To the manufacturer showing the greatest variety of articles 

 made from rubber, or it may be for one article only. 



2. Or it may go to a manufacturer of machinery, or for some 

 labor-saving device that would benefit manufacturers or planters. 



3. Or for some simple invention of great value to all connected 

 with the rubber industry. 



4. Or to the exhibitor of some article which demonstrates how 

 largely rubber may bo used for general and commercial use in a way 

 hitherto unknown. 



It will be seen from the foregoing list tliat the competition is 

 practically thrown open to every manufacturer, chemist, planter, 

 inventor, maker of machinery, etc., irrespective of nationality, 

 the award being made strictly for the exhibit made. 



All that is necessary is that the exhibit be in the hands of the 

 Awards Committee on or before the night of May 1, as the 

 entries will then be closed, but entries received subsequently, 

 the envelopes of which bear the post mark May 1, no matter 

 where mailed, will be accepted as within the time liir.it. All 

 entries must be sent full carriage prepaid, addressed Awards 

 Committee, International Rubber and Allied Trades Exhibition. 

 Royal Agricultural Hall, Islington, London, N., and must be 

 marked as to which competition they are to be entered for ; thus 

 exhibits intended for the competition above referred to must 

 be marked "The President's Trophy." 



There is nothing to prevent a competitor entering as many 

 competitions as he may wish, provided the conditions of each 

 are complied with, nor is any special printed form nec^essary. 

 Any further information desired may be obtained by addressing 

 A. Staines Mandcrs, organizing manager. International Rubber 

 and Allied Trades Exhibition, 75 Chancery Lane, Holborn, 

 London, W. C. 



President's Trophy .\t the Ri-bber E.xhibitiov. 



The cup, as our illustration shows, is a handsome and artistic 

 piece of silversmith's work and bears on the front side the 

 inscription, "International Rubber and Allied Trades Exhibition, 

 London, June and July, 1911. Patron, His JMajesty, the King; 

 President, Sir Henry A. Blake ; A. Staines Manders, Manager, 

 and Miss D. Fulton, Secretary." On the reverse side the in- 

 scription reads: "President's Trophy. Awarded to " 



the name of the succesful competitor. 



The botanical garden of the Museu Gceldi. at Para. Brazil, 

 has increased in area more than threefold in fifteen years. The 

 director of this institution, Dr. Jacques Huber, writing in the 

 Bulletin of the Pan American Union (Washington: January. 

 1911) says of the trees and shrubs cultivated in the garden; 

 "Some of them are of great industrial value, as for instance, the 

 species of Hevea. Of this plant the garden possesses the richest 

 collection in the world. The experimental garden, originally 

 designed for experimental cultivation of plants having a commer- 

 cial value, is wholly occupied by the various .Amazonian rubber 

 trees, chiefly species of Hevea and Sapium." The Para museum, 

 it will be remembered, was dealt with at length in a series of 

 letters from the Amazon by the Editor of The Indi.\ Rubber 

 World last year.
