which has a strong odor of sassafras. Different ones of these are known 
as Icappla , ruan, medang lada and calingad in the Malay Archipelago. 
It is probable that some of these at any rate would make good substitutes 
for camphorwood in the manufacture of insect-proof boxes. 
The Borneo camphorwood is obtained from species of Dryobalanops 
(see p. 509), of the family Dipterocarpacece , and does not have an odor 
like camphor, except in the neighborhood of the camphor deposits. This 
wood is not used for cabinet work.

CORKWOODS. 
A number of plants, from widely different families, and mostly tropical, 
are found to produce what is known as corkwood; i. e., a wood which 
more or less resembles time cork in its physical properties. 
These woods show differences in structure but agree in having very 
thin-walled elements, which are empty or filled with air in the dry wood. 
These uniformly thin-walled elements cause the wood to have a very 
low specific gravity and to be exceedingly soft. 
Very uniform corkwood is produced by Ceiba pentandra (L.) Gaertn. 
and Bornbax malabarica DC. Alstonia scholaris (L.) R. Br. furnishes 
another type of corkwood. The structure is varied by numerous fine 
parallel concentric lines of wood parenchyma. Erythrina indica Lam. 
and other species have corkwood of a quite different type — wide con- 
centric belts of wood parenchyma having between them rather narrow 
belts of denser tissue. The vessels are also rather large. Still another 
type of corkwood is that furnished by the roots of Sonneratia pagatpat 
Blanco and other species. Here the wood is very homogenous in structure 
and very like a fine white cork. Some other woods which furnish cork- 
wood from their stems or roots are Tetranthera amara ISTees, and species 
of Xylopia, Anona , Hibiscus, Dyera, etc. 
The corkwoods are commonly used as floats for fishing nets and as 
material for the manufacture of the crude carvings so common among 
wild tribes in Borneo.

INCENSE WOODS. 
Certain woods are valued because of their ability to produce a pleasant 
odor when burned. Several of these have, since the most ancient times, 
been employed in religious ceremonies. The best known of these is 
Santalum album L., mentioned in the Hebrew Scriptures as algum or 
almug. 
The lign aloes or lignum aloes of the Scriptures is the same as the 
eaglewood of commerce and is produced by Aquillaria agallocha Roxb. 
( Aloexylon agallochum Lour.), and other related species, of India and 
Malaya.
