THE PHYSIOGRAPHY OF LABRADOR 69 
the range in Ungava Bay is said to be as much as fifty feet. 
In any case the range in this bay is one of the greatest 
recorded in the world. 
Since the magnetic pole lies to the north-northwest of 
Hudson Bay, the magnetic variation is very high on the 
Labrador coast. At Battle Harbour it is 40° west; thence 
it increases until it is more than 53° to the west at Cape 
Chidley.. The visitor cannot fail to be struck by the fact 
that, during auroral displays, the middle of the illuminated 
arc, which flames over the magnetic pole, lies to the north- 
west, far from the north star. 
It should be emphasized that the charts of the region 
north of Hamilton Inlet are of little or no practical value 
to the navigator. They are only of value in giving general 
directions and in furnishing a crude pictorial idea of the 
coast. 
The climate of Labrador is not excelled anywhere in 
the world for its bracing and invigorating effect. Testi- 
mony gathered from hundreds of workmen, prospectors, 
visitors, sailors, fishermen, officials, lumbermen, and 
scientific men have shown that, without exception, their 
general health has improved, and they have been able to 
sleep quite a material proportion of the twenty-four hours 
longer than at their own homes. Of this in my own ex- 
perience of seventeen years, I have had many remarkable 
instances. 
Labrador has no endemic disease, and though, like all 
subarctic countries, it is the home of many mosquitoes, 
there is no malaria. Notwithstanding the great number 
of Eskimo dogs bred and kept in the country, I have 
never known nor heard of a single case of either hydro-
