While the work of the survey during all these years appeared in a 

 regular series of annual reports, the growing interest taken by the 

 general public in its progress, and the apparent necessity for presenting 

 the conclusions arrived at in a more compact form, at length reached 

 such a point that Sir William Logan, assisted by Dr. Hunt, brought 

 out, in 1863, the volume now known as the " Geology of Canada." In 

 this the investigations and results of the preceding twenty years were ad- 

 mirably summed up, and the latest views of structure of all the formations 

 from the Laurentian to the carboniferous clearly stated, both from the 

 standpoint of the stratigrapher and the paleontologist, while the second 

 part contained an immense amount of the most valuable information 

 relative not only to the chemical comuosition and origin of the various 

 rocks but to the value and distribution of the most important of our 

 economic minerals. 



In connection with this volume, and designed to accompany it, the 

 great geological map of Canada and the adjacent Northern States was 

 published in 1866, of which it may be rightly said that no more 

 beautiful work of the kind has ever been presented by this or any other 

 survey j a work entailing an enormous amount of labour, and reflecting 

 the greatest credit upon all engaged in its compilation, and in the 

 delineation of the exceedingly complicated geological lines there laid 

 down. This great work will always stand as the map far excellence, 

 and can always be pointed to with a feeling of pride, nob only by the 

 members of the survey itself, but by every Canadian who feels an inter- 

 est in the successful carrying out of the study of geological science in 

 our own country. Bailing alkthese years of hard work in the field by 

 the officers and staff other matters, involving quite as serious labour, 

 were being presented from time to time. The great exhibitions at 

 London, Paris, and Dublin, to which the survey sent lai'ge and charac- 

 teristic collections, both of rocks and minerals, which set forth in a 

 forcible manner the great wealth of the country in this respect, were 

 productive of much good, but involved an immense expenditure of time 

 and energy. The museum and offices at Montreal were constantly 

 visited by scientific men from ail parts of the world, who might be pas- 

 sing through, as vrell as by others seeking information on various 

 points, and from the old workshop on St. James and St. Gabriel streets
