On the Forest-Trees of British Guiana, and their Uses in Naval 

 and Civil Architecture ; by Sir Robert H. Schomburgk, Ph.D. Sfc. 



The trees are mostly indicated by their colonial names, but to many 

 of them Sir R. Schomburgk has been enabled to add their scientific 

 designation. 



Souari, Sewarri ov Sewarra (Pekea tuberculosa, ^«^J/.)- Of large 

 size and very abundant ; excellent for ship-buitding, mill-timber and 

 planks, and may be obtained from 20 to 40 feet long, and from 16 to 

 20 inches square. 



Siruaballij Sirwaballi, Siverballi. There are four varieties or per- 

 haps species of this tree, which belongs to the family of Laurineae. 

 They are distinguished as black, brown, yellow and white Siruaballi. 

 Its spicy smell and bitter taste preserve it from the attacks of worms, 

 either in or out of water, on which account it is in great request for 

 planking colonial crafts. 



DakumbalU. Grows on the side of rivers, and is not much used. 



Marsiballi or Accuribroed. A tall straight tree, but not of large 

 size. Wood hard and strong, but not very durable when exposed to 

 alternations of wet and dry weather, for which reason it is only used 

 in house-framing and inside work. When dried it is frequently used 

 for torches. 



Turanira or Bastard Bully-tree. Tall, straight, of large size, and 

 abundant on the banks of the Demerara River. Makes good planks 

 and framing-timbers for inside work, but is not durable when exposed 

 to the weather. 



Suradani or Suridani. Plentiful and of large size ; principally in 

 request for planks and timbers of colony crafts. It is of a light red 

 colour. 



Kautaballi or Kutaballi. Grows chiefly on the sand-hills which 

 form the first elevations on receding from the sea-coast. Very hard, 

 and much used for beams and inside work, but not durable when 

 exposed to the weather. ^ 



Cakaralli or Kukaralli. Mostly found on rising ground along the 



banks of rivers, and belongs to the tribe of Lecythideaj. Its straight- 



ness and large size (from 30 to 40 feet long and from 6 to 1 4 inches 



square) would qualify it for masts or spars for colony crafts ; but its
