Several exhibits were prepared and placed in the Museum. These 
exhibits are specially of an economic character. The museum cases for 
the systematic collection are now being made in our own shops. Early in 
the year a museum case designed by this office and built by the Museum 
cabinet makers was filled with a special collection of Canadian ornamental 
stones. This case proved so satisfactory and won such universal approval 
that it was decided a few months ago to accept the plan as a permanent 
one, and a number of cases to cover our requirements are under course of 
construction. 
In addition to identifying a large number of specimens for the system- 
atic collection, the following studies have been contributed to Canadian 
mineralogy.

The Division of Mineralogy of the Geological Survey was one of the 
first institutions in America to distribute mineral collections. Several 
years ago these collections were given away free of charge, but the demand 
became so great that it was impossible to meet it. Our mineral collections 
are now distributed at a price which, though less than what they cost, 
serves to discourage unjustifiable requests. This year our output of collec- 
tions almost doubled that of any preceding year since we commenced 
charging for them. The collections were distributed as follows :
