112 FOREST CULTURE AND 
ries. A kind of Jute (Corchorus olitorius) succeeds 
as far north as the Mediterranean, and grows wild 
with the Sun Hemp (Crotalaria juncea ) in tropical 
Australia; the latter plant comes naturally almost 
to the boundaries of our colony. A Melbourne rope- 
factory offers £36 for the ton of New Zealand Flax, 
and can consume six tons per week. Hemp, used 
‘ since antiquity, produces, along with its fibre, the 
Hypnotic Churras. England imported, in 1858, 
Hemp, to the value of more than £1,000,000.* This 
may suffice to indicate new resources in this direction. 
For Sumach our country offers, in many places, the 
precise conditions for its successful growth, as con- 
firmed by actual tests. Tannic substances, of which 
the indigenous’ supply is abundant and manifold, 
would assume still greater commercial importance by 
simple processes of reducing them to a concentrated 
form. How on any forest river might not the Fil- 
bert-tree be naturalized ; on precipitous places, among 
rocks, it would form a useful jungle, furnishing, be- 
sides, its nuts, the material for fishing-rods, hoops, 
charcoal crayons, and other purposes. From a single 
forest at Barcelona sixty thousand bushels are obtain- 
ed ina year. (For these and many other data brought 
before you in this lecture you may refer further, most 
conveniently, to a posthumous work of the great Pro- 
fessor Lindley, Treasury of Botany, edited by Mr. 
Th. Moore, with the aid of able contributors.) Even 
the Loquat would attain in our forest  glens the size 
of a fair, or even large tree. 
* The import of Hemp and Jute into Britain during 1868 was three mil- 
lion two hundred and eighty-one thousand two hundred and sixty-eight 
hundred weight; during 1869, three million five hundred and fifty-one 
thousand eight hundred and thirty-eight hundred weight.. The undressed 
Hemp imported in 1868 was valued at £2,022,419.
