of perfection. Another, and in native practice not the least 
important, recommendation of the American short-stapled 
Cottons, is the rapidity with which they mature their first 
crop, (the time required being even less than that for our 
native Cotton,) and their Jarger produce of wool in propor- 
tion to the quantity of seed. On the other hand, however, 
the seeds are considered less wholesome for feeding cattle; 
and should such be generally found to be the case, it will 
prove a very heavy drawback, if not an almost insurmount- 
able obstacle, to its general introduction as an article of 
native agriculture." 
The DIPTEROCARPE® are almost exclusively of Indian 
origin; we have the following interesting account at p. 86, of 
their properties and uses. “ These are various and import- 
ant. Almost every species of the Order abounds in balsamic 
resinous juice, in very general use in every part of India, and 
well known to Europeans under the common English names 
of Dammer, and Wood oil, according as it hardens or remains 
fluid on exposure to the air. That kind which is drawn from 
the Shoreas or Vaticas, and Vaterias, hardens, and forms 
Dammer and Piney ; that from Dipterocarpi retains its fluid- 
ity, and constitutes the Wood oil of the bazaars. Some of 
the species produce a fragrant resin, which is burnt in the 
temples as incense. Dammer is used in India for most of 
_ the purposes to which pitch and rosin are applied i in Europe. 
Wood oil, either alone, or thickened with dammer, supplies a 
common, but useful varnish for wood, possessing the valuable 
Property of, for a long time, repelling the attacks of the 
White ants, as well as resisting the influence of the climate. 
The Camphor-tree of Sumatra is a species of Vatica (Shorea 
camphorifera, Roxb.) and produces the finest Camphor.. A 
variety of other trees are said to afford this curious substance; 
but none are equal to this, either in quality or quantity. 
The Vateria Indica (Chlorozylon Dupada of Buchanan and 
Ainslie, and Pinne Marum of the Hindoos) yields a resin, —

other species native of none the finer Cr a t A
