most vertical position. Fig. 12 shows a section of one of them, and most 
of the others are like it. It will be seen that the pyroxene lines both 
sides of the vein and the apatite comes in the middle. The strike and 
the width of nine of these veins were found to be : 
N. 11° W., six inches wide. Red apatite. 
N. 10° W., eighteen inches wide. Red apatite. 
N. 8° W., one to three feet wide. Red apatite. 
N. 20° W., one foot wide. Red apatite. 
N. 8° W., one foot wide. Red apatite. 
N. 35° W., six inches to one foot wide. Red apatite. 
N. 36° W., one foot wide. Red apatite. 
N. 45° W., one foot wide. Red apatite. 
N. 30° W.,one foot wide. Red apatite. 
The country gneiss is much contorted and strikes in various direc- 
tions. It has an almost vertical dip. On the same properties there are 
also other veins running in various directions, but they are generally of 
small extent. In one place a vein was seen composed on one side of 
a band of apatite and on the other of a band of pyrites of iron contain- 
ing masses of talc.

Another instance of a banded vein occurs at Mud Lake, Templeton 
Township, Ottawa County, Quebec, where apatite, mica, and pyroxone 
form the contents of the vein. 1 But it is generally in the Ontario dis^ 
trict that the banded structure is most often seen. 
In the township of North Burgess, Lanark County, Ontario, are many 
e xamples of phosphate-bearing veins, some of which can be traced for
