THE ISOCHLORS OF NOVA SCOTIA. VICKERY. 365 



and as these two points are cqui-distant from salt water, 

 a clearly defined line (the ten normal) can here be drawn. 

 Carleton showed 8,4, and a brook a little further up 8.2. 

 A brook just below Kemptville 7.0, and a large stream above 

 Kemptville, 28 miles from Yarmouth, 5,1. 



This series shows a continuous decrease, running from 

 the coast line inland, and it is noticed that the observation 

 of 5.1 near Kemptville, is about the same distance from the 

 salt water as the observation 5.0 at West Northfield 

 (Series 2). 



With reference to the high chlorine content of wells 

 and brooks near Yarmouth, the prevailing winds are to some 

 extent responsible, for during heavy, south westerl}^ gales, 

 windows in the lower parts of the town of Yarmouth are 

 sometimes covered with an encrustation of salt carried, 

 evidently in spray from the breakers on the rocky coast, 

 full}^ two miles away. 



Series Four. This consists of only three or four observa- 

 tions, one of a sample taken from a well at Musquodoboit 

 Harbor, which showed 4.6, and a few observations in the 

 vicinity of Middle Musquodoboit; the lowest being 4.4 from 

 a brook running about two miles above the river. 



Series Five. At the mouth of fictou Harbor a brook 

 gave 10.4, two or three brooks south of New Glasgow 4,6 

 and 4,1; brooks at Kerrogare and eastward 5.1, 5.3 and 5.4. 

 Melrose Lake 5.1 and Sherbrooke Lake 7.0, again showing 

 the decrease and increase. 



Series Six. A brook supplying the reservoir at Antigonish 

 gave 6.8, defining an important corner of the seven normal. 

 A brook at Port Mulgrave gave 8.2, locating the ten normal 

 practically on the Strait of Canso shore. A brook near 

 PhiUp's Harbor gave over 15, a value recalling those obtained 

 near Yarmouth at the other end of the Province.
