nearly such as it may be conceived to have been when first 

 uncovered by the departure of the sea." The whole district is 

 intersected with delightful 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 from 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. 



The 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
