placed between a settlement and a swamp, besides absorbing 

 moisture, would to a certain extent intercept the malaria. In 

 the last Burmese war, he saw a stockade built of teak a quarter of a 

 mile in length, burn so well that next morning only a few blackened 

 sticks remained. Years ago, he had suggested the growth of 

 mahogany in Bengal. 



Colonel Beddome said teak seemed to require the influence of the 

 south-western monsoon, and did not grow beyond 20° north latitude. 

 In the plains of Bengal there was not sufficient rainfall. He should 

 say 150 inches of rain a year was necessary for the growth of teak.,, 

 Mahogany appeared to be the Indian tree of the future. 



The Chairman, Colonel Michael, C.S.I., in his concluding remarks, 

 referred to the magnificent display of teak from India and other 

 Eastern dominions at the late International Forestry Exhibition. 

 Divers Eastern woods shown were also recognised to be of commercial 

 value. At the close of the Edinburgh Exhibition, a local cabinet- 

 maker and builder purchased a number of pieces of almost unknown 

 woods, at the price of 5 s. per cubic foot all round, which was a clear 

 proof that if woods of that description were put on the market, a 

 remunerative price could be obtained. Amongst these woods were 

 Ptcrocarpus indicus, Shorca ohtusa, Ccdrcla toona, Fentace Burmanica, 

 PterocarpU'S marsupium, Lugerstrcemia fios regincc, Shorca obliisa, 

 Shorca Siamcnsis, Fagrcca fragrans, Tcrminalia glabra, Hopea 

 odorata, Sandoricivm indicuvi, Acacia arabica. 



SAND-PLAINS OF BELGIUM AND SAND-DUNES OF 

 HOLLAND, AND THEIR TEACHINGS. 



{Concluded.) 

 BY THE KEV. J. C. BROWN, LL.D. 



I MIGHT have mentioned that sand-dunes abound everywhere 

 upon lee-shores. We need not leave the coasts of Europe to 

 find opportunities in abundance to study their formation and 

 structure and characteristic phenomena. 



Strand-dunes appear along the southern shore of the Baltic, in 

 Liefland, Courland, Prussia, Pomerania, and Mecklenburg ; and the 

 Esthonian islands of Oesel and Dago ; on the southern coast of the 

 German Ocean, especially in the projecting coasts of the islands 

 Helgoland, Wangeroog, Norderney, Borkum, etc. ; then on the coast 

 of Holland and Belgium, and points of the coast of Suffolk, along 

 the whole western coast of the Cimbrian peninsula of Schleswig- 

 Holstein, and Jutland, and Denmark ; also on the western islands 

 Sylt and Nahr ; on the French coast of the Atlantic, in Brittany,
