THIRD INTERNATIONAL RUBBER AND ALLIED TRADES 



EXPOSITION. 



New York City, September 23rd to October 3rd, 1912. 



The above illustrates the New Grand Central ders has arranged for the Third International 

 Palace, 46th to 47th Street and Lexington Ave- Rubber and Allied Trades Exposition, from 

 nue, New York City, where Mr. Staines Man- September, 23rd to October 3rd, 1912. 



GROWTH IN GBRTH OF TREES. 



The following table is from figures supplied 

 by Mr Ridley, the Director of the Botanic Gar- 

 dens, Singapore. It shows the growth in girth, 

 at 3 feet from the base, that may be expected 

 from a fairly and treated rubber tree. The first 

 two years' growth is very variable. During the 

 next three years the girth should increase 6 in. 

 every year. From the fifth to the 15th year the 

 increase should be 3'4 in. annually, aud from 

 then on to the 20th year 2-3 in. Close planting 

 will reduce this increase materially after the 

 10th year, and probably before that. Too closely 

 planted trees sooner or later cease to show any 

 material increase. The figures are for trees 

 grown in good soil without manuring and with 

 wide planting for example, 20 by 20 feet. An 

 individual tree Mr Ridley has measured shows 

 at 14 years a girth of 79 in. (this in the forest 

 among other trees) ; another tree 32 years old 

 is now 124 in. in girth. A rubber tree should 

 be ready for tapping in its fourth or fifth year, 

 according to the conditions under which it is 

 growing :—

THE PRIZES OP PEACE. 



While Italy as a nation is busily pursuing 

 the fruits of war, Turin is distributing the 

 laurels of of peace. The awards at the Interna- 

 tional Exhibition have just been announced, 

 and they indicate that the very h'gh standard 

 attained by English exhibits has not gone un- 

 regarded. One firm alone, Messrs. Burroughs 

 Wellcome & Co., the manufacturing chemists, 

 has securod no less than thirteen awards, con- 

 sisting of eight grand prizes, two diplomas of 

 honour, and three gold medals. This probably 

 constitutes a world's record in awards received 

 by a single firm at an exhibition open to all 

 nations.
