of green hornblende and white feldspar, which forms a ridge about one 
hundred yards wide parallel to the strike of the country gneiss. To 
complete the list of rocks found in the apatite districts it is necessary 
to mention the large veins of crystalline calcite, which often contain 
serpentine and chrysotile. In the occurrence of these veins this Cana- 
dian apatite region is in marked contrast with that of Norway, where 
little calcareous matter is found.

The apatite of Canada is found occurring in a great variety of ways. 
Prof. T. Sterry Hunt regards most of the workable deposits as veins, 
but he thinks there are also some deposits which occur in beds. He has 
discovered small masses of apatite marking the lines of stratification in

the pyroxene. 1 An instance of this was seen by the writer in an old pit 
in Buckingham Township, Ottawa County, Quebec, where the apparent 
lines of stratification were marked by bands of apatite (see Fig. 0).
