WORKS ON FORESTRY, 
By the Rev. J. C. BROWN, LL.D. 
I.—Hydrology of South Africa; or Details of the former 
Hydrographic Condition of the Cape of Good Hope, and of Causes 
of its present Aridity, with Suggestions of appropriate Remedies 
for this Aridity. Price 10s. 
In this the desiccation of South Africa, from pre-Adamic times to the 
pret day, is traced by indications supplied by geological formations, 
‘by the physical geography or the general contour of the country, and by 
arborescent productions in the iuterior, with results confirmatory of the 
opinion that the appropriate remedies are irrigation, arboriculture, and 
an improved forest economy ; or the erection of dams to prevent the 
escape of a portion of the rainfall to the sea—the abandonment or restric- 
tion of the burning of the herbage and bush in connection with pastoral 
and agricultural operations—the conservation and extension of existin; 
forests—and the adoption of, measures similar to the réboisement acid 
-gazonnement carried out in France, with a view to prevent the formation 
sof torrents, and the destruction of property occasioned by them. 
II.—Water Supply of South Africa, and Facilities for the 
Storage of it. Price 18s 6d. : 
In this Volume are detailed meteorological observations on the humi- 
‘dity of the air and the rainfall, on clouds, and winds, and thunder- 
storms ; sources from which is derived the supply of moisture which is 
at present available for agricultural operations in the Colony of the Cape 
of Good Hope and regions beyond, embracing the atmosphere, the rain- 
fall, rivers, fountains, subterranean streams and reservoirs, and the sea; 
and the supply of water and facilities for the storage of it in each of the 
divisions of the colony—in Basutoland, in the Orange River Free State, 
in Griqualand West, in the Transvaal Territory, in Zululand, at Natal, 
and in the Transkei Territory. 
III.—Forests and Moisture; or Effects of Forests on Humidity 
of Climate. Price 10s. 
In this are given details of phenomena of vegetation on which the 
meteorological effects of forests affecting the humidity of climate depend 
—of the effects of forests on the humidity of the atmosphere, on the 
humidity of the ground, on marshes, on the moisture of a wide expanse 
of country, on the local rainfall, and on rivers—and of the correspond- 
ence between the distribution of the rainfall and of forests—the measure 
.of correspondence between the distribution of the rainfall and that of 
forests—the distribution of the rainfall dependent on geographical posi- 
tion, determined by the contour of a country—the distribution of forests 
affected by the distribution of the rainfall—and the local effects of, 
forests on the distribution of the rainfall within the forest district. 
IV.—The Forests of England ; and the Management of them 
in Byegone Times.. Price.6s. 
Ancient forests, chases, parks, warrens, and woods are described ; 
details are given of destructive treatment to which they have been sub- 
jected, and of legislation and literature relating to them previous to the 
present century. .
