with the permanent telegraph station at Chateau Bay, 
Labrador, and thence by existing lines with New York; 
by the same means communication with the Hxpedition 
will be possible for some of the distance. In February, 
1906, the sledge party intended to move forward for the 
northern dash. The ship carries two years’ supply. A 
permanent sub-base is established at Cape Sabine, west 
coast of Smith’s Sound, where the services of the 
necessary Eskimos will be secured. The vessel will be 
forced through Kane Basin and Kennedy and Robeson 
Channels to the north coast of Grant Land, or of Greenland, 
if the conditions compel it, and there winter within the 
500 miles limit of the Pole. This dash may occupy five 
months. In the event of the Roosevelt failing to force 
Kennedy and Robeson Channels during the first summer, 
the dash for the Pole will be postponed until the following 
February, 1907. 
Reinforced Concrete.—During the session just ended a 
paper on steel and iron reinforced concrete was before the 
Society, and the following interesting preliminary report 
issued by the Mines branch of the Canadian Department 
of the Interior bears on this question; it has reference to 
raw materials, manufacture, and uses of hydraulic cements 
in Manitoba. It has been drawn up by Mr. J. Walter 
Wells, and involved an examination of the limestones, 
marls, clays, shales and coal deposits of the province— 
particulars are added of the cement mills in North Dakota, 
in Minnesota, and in South Dakota, and much information 
is given regarding the manufacture of cement from the 
raw materials available, that cannot fail to be of practical 
value in furthering the cement industry of Manitoba and 
generally throughout the world. In that province, timber 
is becoming scarce, and suitable stone and bricks are 
expensive; cement is therefore coming into increasing use
