Peppermill Dam (see Plate CXV.) lies little more than a mile from 

 Kincardine, on the northern shore of the Firth of Forth, and about 2 miles 

 from Gartmorn Dam. It is nearly a mile in length from east to west, with 

 a maximum breadth of a quarter of a mile in the central part, whence it 

 narrows towards both ends. The superficial area is about 90 acres, and the 

 drainage area nearly 2 square miles. The eastern portion is shallow, the 

 water deepening towards the west end, where the maximum of 17 feet was 

 recorded. The volume of water is estimated at 34 million cubic feet, and 

 the mean depth at 8J- feet. When surveyed on May 17, 1905, the elevation 

 was 158-9 feet above the sea, as compared with 160-5 feet found by the 

 Ordnance Survey officers on September 14, 1894. The following tempera- 

 tures taken in the deepest part show a range of less than 3 Fahr. from 

 surface to bottom, a fall of l-5 Fahr. being recorded between 5 and 10 

 feet :

Moor Dam (see Plate CXV.) is a little shallow basin lying between 

 Peppermill Dam and the town of Kincardine. It is very irregular in out- 

 line, the maximum diameter from north to south being nearly half a mile, 

 and the superficial area about 49 acres. Towards the western shore several 

 soundings in 5 and 6 feet were taken, the northern and eastern parts, 

 equal to three-fourths of the total area, being less than 5 feet in depth, the 

 mean depth being estimated at 3j feet, and the volume at 7 million cubic 

 feet. When surveyed on May 17, 1905, the elevation was 145*4 feet above 

 the sea, as compared with 146*8 feet determined by the Ordnance Survey 

 on September 12, 1894. The temperature of the surface water was 

 60-5 Fahr. 



Burntisland Reservoir (see Plate CXVI.) lies about a mile from Aber- 

 dour, and less than 3 miles from Burntisland, on the northern shore of the 

 Firth of Forth. It is most irregular in outline, and about half a mile in 

 maximum diameter, with a superficial area of about 43 acres. Very deep 

 water occurs close to the sluice at the southern end, where the maximum 

 of 39 feet was found, and a small area exceeding 20 feet in depth runs 

 along the south-eastern shore, but more than half of the bottom is covered 

 by less than 10 feet of water, the mean depth being estimated at nearly 

 12 feet, and the volume at 22 million cubic feet. When surveyed on 

 May 19, 1905, the elevation was 290-0 feet above the sea. The following 

 temperatures taken in the deepest part show a constant temperature down
