VI.—SuppLemMentary Notes on Drier IcE AS A TRANSPORTING 
AGENT.—By WALTER H. Prest, Bedford, N. S. 
(Read 10th March, 1902.) 
A second visit to Labrador has largely confirmed my obser- 
vations of 1900*, and convinced me that the transportation of 
debris by floating ice has been greatly overrated. Although 
again in the midst of icebergs and field-ice for over three months, 
I could tind extremely few icebergs carrying earthy material. 
The field-ice, in huge pans, often several acres in extent, and 40 
or 50 feet thick, seemed almost as destitute of debris as the 
bergs. The only drift-bearing ice was comparatively thin, 
usually much broken up and refrozen, and without doubt formed 
in shallow coast waters. Near the Straits of Belle Isle, the little 
remaining dsbris on this was nearly all marine or much mixed 
with marine organisms. Further north, especially in the bays, 
the transported material was largely of littoral origin. This 
difference was owing to the fact that the surf had nearly 
completed its cleansing process before the arrival of the ice at the 
Straits. Some of this debris-bearing ice, when examined closely, 
is found to be merely discoloured by a very fine, dust like 
material, probably not s355 part of the weight of the ice bearing it. 
I had the pleasure of seeing how the harbor ice received its 
burden, on a shallow, sandy shore called the Strand, a short 
distance north of Sandwich Bay. Parts of this coast, even in 
the month of June, were fringed with ice near high-water mark. 
Over this ran rivulets carrying mud and gravel from the banks 
above, while the waves contributed their share of debris in the 
form of sand, seaweed, and shells, 
One fact strongly supporting my contention of 1900, was 
brought the more prominently to my notice as I went north. 
This was the ever increasing quantity of debris on the thin ice
