neai'ly such as it may be conceived to have been when first 
uncovered by the departure of the sea." The whole district is 
intersected with dehghtful valleys, through which run several 
rivulets, that flow into the Wey from various sources, amongst 
which is one that is rendered classical by the delightful author 
of Selborne. This, meeting the Blackdown stream at Headley, 
is joined by the Alton and Farnham branch, at Tilford-bridge, 
where they form a considerable stream. From this point the 
Wey proceeds in an eastwardly direction by Elstead &c., re- 
ceiving in its course several small streams fi*om the neighbour- 
hood of Thursley and Witley, one of which takes its rise in the 
Devil's Punchbowl, from which source flows a delicious stream, 
as clear as crystal. The river, after passing by Godalming, from 
whence it is navigable by the addition of a canal, runs through a 
long line of pleasant meadows to Guildford, and in its progress 
receives the tribute of two additional streams, the Arun canal 
and the Tillingbourne, which add much to its importance ; it ul- 
timately falls into the Thames near Weybridge. According to 
Mr. Stevenson, " the waters of the Wey are of much less ferti- 
lizing quality than other streams in Surrey. This is attributed 
to the sandy country through which the Wey flows in the begin- 
ning of its course, and to the large quantities of sand which, after 
every heavy shower, are washed into the river from the steep hills 
near Godalming." 
Localities of Plants. — From the diversity of soil included in 
the foregoing sketch, it is evident that many of our rarer plants 
may be expected to be met with. The Flora of the district will 
be better elucidated under the three following divisions. 
TJie first division comprises the chalk and adjoining strata of 
London clay and gait, forming a large portion of the northern 
boundary. This district is rich in Orchidaceae and other calca- 
reous plants. The extensive quarries at Compton and Wan- 
borough will afford a rich treat to the admirer of this beautiful 
and interesting tribe of plants. Orchis pyramidalis, Gymnadenia 
conopsea, Listera ovata, Aceras anthropophora, and Herminium
