364 THE ISOCHLORS OF NOVA SCOTIA, VICKERY. 



Series One. Several samples in the vicinity of Halifax, 

 Melville Cove, Fairview, Rockingham and Bedford ran from 

 6.5 to 4.8; Grand Lake 4,1, Truro 4.9, showed a decrease 

 to a minimum and then an increase. An observation of 4.4 

 at Middle Musquodoboit closely corresponded to these. 



Series Two. At Margaretville a small brook running 

 over the cliff into the Bay of Fundy showed 33; another 

 a mile back over the mountain, 8.5, A small brook on the 

 top of the mountain, under ideal conditions, gave 10.1, while 

 a brook at Spa Springs showed 9,8. These observations, 

 although showing an increase on the line over the mountain, 

 are checked by an observation from a small spring by the 

 roadside of 10.4, and the Spa Springs brook itself, 11.5, 

 Middleton tap water, derived from a lake on the South 

 Mountain, somewhere near Nictaux, showed 6,6, Alpena 

 6,7, Lake Pleasant at Springfield, 4.6 (sample taken from 

 lake). New Germany 3.8 (the lowest of the three observations, 

 the others being 4,3 and 4,4), Northfield 4,3, WestNorthfield 

 5,0, Bridgewater 5.4. A brook six miles below Bridgewater 

 running into the salt estuS,ry of the LaHave 7.5, completes 

 the series. This series shows a distinct decrease to a minimum 

 at New Germany and a clearly defined increase from New 

 Germany to the mouth of the LaHave. 



Series Three. A number of observations in the vicinity 

 of Yarmouth, ranging from 65 in a sample taken from at 

 well in a narrow sand spit between the Bay of Fundy and 

 Yarmouth Harbor to 21.5 in a well near Yarmouth Harbour, 

 under ideal conditions, and numerous observations of 16 

 and 17 taken at various points within a few miles of the town, 

 show very clearly the influence of the salt water and salt 

 water estuaries in that vicinity. Two series of observations 

 were made; one covering a small section of country from the 

 northern part. Lake George to Lake Annis (three or four 

 miles) another over a twenty mile stretch from Decrficld to 

 Kemptville. Lake Annis showed 10.0 and Decrfield 10.2,
