BATHYMETRICAL SURVEY OF 
This series shows a range of temperature throughout the 60 feet of 
water amounting to 10°*4, the greatest fall being one of 5°-3 between 
15 and 20 feet. 
Loch Shechernich (see Plate XXXIII.). — ^Loch Shechernich (or 
Bainie), a small loch in Glenshee, situated amid fine mountain scenery, 
is a good trout loch, but strictly preserved. It flows by the Allt Mor 
into Shee water, thence by the Black water into the river Ericht, a 
tributary of the river Isla. Its shores are low and peaty, rising 
gradually to the surrounding heather-clad hills. Near the centre of 
the loch is an artificial island composed of small stones. Loch 
Shechernich trends in an east and west direction, and is nearl}/ half a 
mile in length, and one-fifth of a mile in maximum breadth, the mean 
breadth being one-seventh of a mile, or 31 per cent, of the length. Its 
waters cover an area of about 42 acres, and it drains an area 16J times 
greater — an area considerably over 1 square mile. Thirty soundings 
were taken, the maximum depth observed being 8 feet. The volume of 
water is estimated at 7,364,000 cubic feet, and the mean depth at 
4 feet, or 50 per cent, of the maximum depth. The bottom sinks 
gradually from the west towards the east end, being covered by less 
than 6 feet of water in the western half (to the west of the central 
island), while the greater portion of the eastern half is covered by more 
than 6 feet of water, the maximum depth of 8 feet having been observed 
in three places comparatively close to the east end. The area of the 
lake-floor covered by less than 5 feet of water is over 31 acres, or 75 per 
cent, of the entire area of the loch. Loch Shechernich was surveyed on 
the same day as Loch nan Eun, July 2, 1903. The elevation above the 
sea could not be ascertained, but from spot-levels it is probably about 
1330 feet. The water in the loch was about its lowest on the date 
of the survey, and apparently rises 1 to 2 feet higher. At 6 p.m. the 
temperature of the water at the surface and at a depth of 7 feet was in 
each case 59°-2. 
Auchenchapel Loch (see Plate XXXIII.). — Loch Auchenchapel (or 
Auchintaple), in Glenisla, near Inverharity, is an artificial loch made in 
1884, and flows by a short stream (Allt na Beinne) into the river Isla ; 
it is a good trout loch, without pike. It trends in a north and south 
direction,, and is over one-third of a mile in length, and over a quarter 
of a mile in maximum breadth, the mean breadth being over one- 
seventh of a mile, or 40 per cent, of the length. Its waters cover an 
area of about 35 acres, and it drains an area 5J times greater — an area 
of one-third of a square mile. Over 40 soundings were taken, the 
maximum depth observed being 17 feet. The volume of water con- 
tained in the loch is estimated at 12,669,000 cubic feet, and the mean 
depth at 8 feet, or 49 per cent, of the maximum depth. Auchenchapel
