ECONOMIC FORESTRY. 493 
Botanical Department of the British Museum a manuscript volume 
by the late John Miers, F.R.S., many years resident in the country, 
entitled, “‘ A Catalogue of the Woods of Brazil; Arranged Alpha- 
betically after their Vernacular Names, their Localities, Dimen- 
sions,” . . . in which many of them are botanically identified. 
** Mattas,” or heavy forests, cover the immense humid lowland of 
Northern Brazil, and occur in belts in the plains of the central and 
southern portions of the empire ; whilst the deciduous woods of the 
mountain slopes are known as “ Catingas.” Language altogether 
fails to picture the luxuriance of the vegetation of equatorial Brazil. 
Among the most valuable timbers of Brazil are—Ccsalpinia 
echinata, ‘‘ Brazil wood ;” 
“ Braziletto wood,” or “ Ibiripatanga,” 
which is hard and heavy, and takes a polish, but is largely used as a 
red dye; C. ferrea, “iron-wood ;” Dalberyia nigra, ‘‘ Jacaranda,” 
or “ Rosewood,” the best of the genus, together with D. latzfolia ; 
Cedrela brasiliensis, the “cedar” of South Brazil; Arauwcaria 
brasiliensis, the pine of the Organ Mountains ; Jimusops alata, 
the “cow tree,” or “‘ Massaranduba” of Para; Physocalymma flori- 
bunda (nat. order, Lythracee), the “ tulip-wood;” Lecythis Ollaria, 
the sapucaya-nut ; Dertholletia excelsa, the Brazil-nut; Ocotea 
major, * Puchury ;” Persea gratissima, the “ Avocado,” or “ Alli- 
gator pear ;” Avicennia, the “* White mangrove,” the bark of 
which is used in tanning; and the numerous palms, of which 
Copernicia cerifera, the ‘ Carnauba,” ‘‘ Wax palm,” is the most 
valuable. But, rich in timber, the Brazilian forests are still richer 
in rubbers, gums, resins, dyes, and medicinal substances, —Siphonia 
elastica and Hancornia speciosa being among the chief rubber trees ; 
Maclura tinctoria yielding fustic, and Bixa Orellana, arnatto, 
FRENCH GUIANA.
