SOME ACCOUNT OF BRIDPORT AND ITS NEIGHBOURHOOD. 33 
but did not cross my path, though I had several false alarms, and have 
since my return had a definite record. 
I found that the }-inch Geological Survey Map is in many par- 
ticulars inaccurate as to the actual surface deposits ; whether by reason 
of its small seale, or intentional in the suppression of detail, 1 know 
not. 
Lest I may seem presumptuous to disagree I call attention to the 
contouring of the district. In the west of the map Gault and Green- 
sand occupy the 500 to 600 contour lines, although the north is badly 
faulted the faults are mostly north of the Lewesdon—Drake North 
Watershed (except near Hooke Park). This watershed is a true water- 
shed, and bounds the Brit Catchment area on the north; the faults 
interfere very little with this Brit Catchment area. 
Many eminences which reach above the contours assigned to the 
mentioned strata, are charted on the Geological Survey as being geo- 
logically below their horizon determined by contour; without being 
too dogmatic, my observations led me to believe this was nearly always 
inaccurate. The localities I visited were as follows :— 
Totter Porcorum.—This village is at 370 feet, in the valley of the 
Hooke River, a tributary of the River Froome. It is situate on the 
Great Oolite. My one and only capture there was the ubiquitous 
Cabera pusaria, which is a hazel feeder, and very widely distributed. 
Hicuer Kinecompe.—A small village one and a half miles to the 
north-west of Toller, higher up the Hooke River, a tributary of the 
Froome, about 420 feet, still on the Great Oolite. My one and only 
capture was Xylophasia rurea, sitting ona gate post close to the Hooke 
River. It is notable however that Genista tinctoria is very abundant 
at Higher Kingcombe. From Higher Kingcombe a charming and 
stony lane runs southward, to an. eminence called Mount Pleasant. 
Curiously enough this lane was mostly remarkable for the entire absence 
of Lepidoptera, no doubt accidental, some very tempting rough 
eround lies to the east of the lane, over the 600 foot contour, but as 
other game was afoot that day I did not stop to investigate it. At 
Mount Pleasant I started to part company with the Geological Survey 
Map. less than half a mile from Mount Pleasant, to the south, lies 
Drake North, and the whole dastance is over the 650 foot contour, and 
is charted Greensand and Gault. I believe this is only correct in 
part. 
- Draxz Norta.—This hill has a long narrow tumulus-shaped cap 
to it. Very sandy and very bracken covered, wooded with Scotch Fir, 
fine specimen trees of considerable age. Here I took Thera variata, 
and I saw, but did not take, Bupalus piniaria, which was of course the 
southern yellow form; it was fairly abundant. I could see no round 
pebbles, though I looked for them, hence, though I considered the cap- 
ping Hocene, I stated it with some trepidation, but Greensand and Gault 
the capping at Drake North is not and never was. The exact height 
I do not know, but the capping is over 700 feet. Behind the capping, 
at about 500 yards, are what look like three huge tumuli, just on the 
western edge of Powerstock Common. These are simply huge mounds 
of solid chalk, all apparently that is left of the heavy coating of chalk 
that once lay over this part of Dorset and frowns at one across the 
valley to the east from Hegardon. 
Drake North marks the dividing line between the Froome water-
