maintained from month to month and from year to year. 

 Various opinions have been hazarded in accounting for 

 the inflow. Whilst the surface of the lake is nearly 180 

 feet above the level of the Bay of Quinte, the bottom is 

 likewise 80 feet above that level. The • source of inflow 

 must therefore be sought for in some locality at any rate 

 200 feet higher than Lake Ontario. A subterranean 

 connection with Lake Erie is a common theory in the sur- 

 rounding district, but this is based on an inaccurate 

 knowledge of the intervening geological levels and struc- 

 ture. One investigator, again, thinks he has found its 

 source in the State of Ohio. Still otliers attribute it to 

 springs nearer home. There is ample room for speculation, 

 but it would be safer to attribute the source of the inflow 

 to districts, comparatively nearer at hand, among the 

 Trenton and Black River Limestones, in the higher ground 

 on the northern side of the Bay of Quinte here. Imme- 

 diately east of Napanee, the Grand Trunk Railway is 127 

 feet above Lake Ontario, and thence north-eastward there 

 is a steady rise in the limestone area and beyond it into 

 the Laurentian, Sharbot Lake being 389 feet above Lake 

 Ontario, and the dip of the limestone rocks is favourable. 

 That the source of the inflow is not attributable to springs 

 from higher ground in Prince Edward County seems to 

 some extent established by the fact that during the long 

 drought in the months of August and September of this 

 year the level of the lake changed but to a small extent. 

 This drought prevailed seriously in the townships fronting 

 on the Bay of Quinte, whilst further back a fair amount 

 of rain fell. Mr. F. S. Wilson, of Glenora, one of the pro- 

 prietors of the mills there, to whom I was indebted for 

 courtesies, and on whose authority the height of the lake 

 above the Bay of Quinte is given, wrote to me on Septem- 

 ber 18th last in reply to my enquiry as to the effect of 

 last summer's drought : " I have watched the level of the 

 water in the lake here and cannot see that the unusually
