122 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 nearly 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
