[BAILEY ] OCCURRENCE OF THE MINERAL ALBERTITE 83 
recently undertaken in the vicinity of St. Joseph College, Memramcook, 
give reason to believe that this supposition will be realized. 
Although the purpose of this paper has been to deal with the 
geological rather than the chemical or economic aspects of the mineral, 
it will probably be of interest to the members of the Society to see some 
illustrations of a possible use of Albertite as exemplified by one of its 
earliest applications upon the part of Dr. Gesner. They consist of 
samples of wood and brick cemented by a material composed partly of 
Albertite and partly of tar, and are noteworthy as marking the beginning 
of the employment of such materials for the manufacture of cements and 
pavements, a process which has since expanded to such enormous pro- 
portions. The specimens have been in the Museum of the University 
of New Brunswick for a period of fifty years, and yet show no visible 
change either in colour, texture or cementing power. In this case, 
of course, the material remained dry. Whether, as in the 
case of the Trinidad and other commercial asphalts, and in artificial 
asphaltene, the material is susceptible to change, either by solution or 
oxydation, as the result of long contact with water, has not, so far as 
I know, been determined.
