 Franklin until as late as August 15. Bolau (1895, p. 8) is the 

 authority for the statement that whalers sought bowheads as far 

 north as 72° north latitude, where, according to Pechuel Losche, 

 they appeared to vanish beneath the ice. The young are born in 

 May, for the most part north of Bering strait.
