tilled with gum. The medullary rays are even and regular, parallel and 

 very distinct. The pores in the Surinam wood are larger and have scarcely 

 any gum tilling, but otherwise the structure is similar to the Demerara 

 variety. 



Pyinkado. Xylia dolahriformis, Benth. Weight, 81 lbs. (my specimen). 

 According to Gamble the weights per foot cube range from 60 to 

 83 lbs. Burma. 



This wood is also known as ironwood. It has recently been determined 

 that the Indian species {X. xylocarpa), known as jamba {q.v.) or irul, 

 is distinct from the Burmese species. It is exceedingly hard, heavy.

strong, and durable. The logs are too heavy to float even after ringing, 

 which makes the transport difficult and costly. When the tree is fresh 

 cut the saw or tool will work it, though with some difficulty, but after 

 long exposure to light and air it is said to be impossible to work. It has 

 been used extensively in India and Burma for sleepers and constructional 

 work with excellent results. It has indeed been suggested that the 

 Burma railways placed obstacles in the way of exporting this timber by 

 charging impossible rates in order to keep the supplies for their own use. 

 A few logs and some planks and boards have been brought to London 

 during the past few years and have found a ready market. The logs 

 were, however, only imported at a hea^'y loss, as the transport was so 

 very excessive ; they were apparently mistaken for a parcel of teak logs.
