ICE-BOKNE BOULDEKS.

a 



sheet of ice is readily formed there, and by this means 

 large quantity of gravel is frequently conveyed from place to 

 place, and heavy boulders also, when the coast-ice is packed 

 into dense masses. Both the large and small stones, thus 

 conveyed, usually travel in one direction like shingle-beaches 

 and this was observed to take place on the coast of Labrador 

 and Gulf of St. Lawrence, between the latitudes 50° and 

 60° N., by Captain Bayfield during his survey in 1839. The 

 line of coast alluded to, is strewed over for a distance of no 

 less than 700 miles with ice-borne boulders, often six feet in 

 diameter, which are for the most part on their way from 

 north to south, or in the direction of the prevailing current. 

 Some points on this coast have been observed to be occasion- 

 ally deserted, and then again at another season thickly be- 

 strewed with erratics.

indebted to Lieut. Bowen, E.N., represents the ordinary 

 appearance of the Labrador coast, between the latitudes of 

 50° and 60° N. Countless blocks, chiefly granitic, and of 

 various sizes, are seen lying between high and low-water
