unfavorable winds prevented sailing on 13 days and pre- 

 vented progress of at least 15 miles on 3 additional days — a 

 total of 16 unfavorable days, or exactly one-half. 



The two chief obstacles to progress were thus the large 

 floes of ice streaming southward along the coast, and winds 

 contrary in direction or insufficient in force. The last 

 trouble from the ice was on July 24, at Ice Tickle; the last 

 day on which we saw any floe-ice at all was July 28 ; and Ford, 

 of Paul's Island, said that the northern end of the ice-sheet 

 passed Ford Harbor about the ist of August. The prevail- 

 ing winds were from the northerly and southerly quarters. 

 During the northward voyage, nearly half the winds (44 per 

 cent.) were northerly, and only 25 per cent, southerly. 

 During the return, about 30 per cent, were from the north 

 and 31 per cent, from the south. 



According to the Newfoundland and Labrador Pilot, 

 "gales are stated to be frequent and violent" on the Labrador 

 coast. The expedition encountered but one or two of any 

 considerable force, during which it was safely in harbor. 

 The Pilot further says that calms are of short duration, "rarely 

 lasting more than one day." About 14 per cent, of the ob- 

 servations taken during the entire trip recorded no wind at 

 all. If we group among the calm days those on which less 

 than 15 miles could be sailed, as well as those when the wind 

 was insufficient to permit any sailing at all, then 25 per cent, 

 of all the days during the northerly voyage were calm, and 

 there were many more when it was calm during a portion of 

 the day. About the same proportion held for the voyage 

 southward. These calm days came quite as frequently sev- 

 eral in succession as singly.

 northward the different harbors at which we touched, the
