beginning was made in earnest. De la Beche, Murchison, 
Sedgwick, and Buckland strongly recommended Logan for the 
office of Colonial Geologist. In August, 1842, he received 
his formal appointment, and speedily entered upon what Sedg- 
wick called his “ Herculean task.” His operations, when de- 
taching fossils from the rocks^ excited sometimes a troublesome 
degree of curiosity, passers-by often supposing that he was 
seeking for buried treasures. 
To give a sketch, even in the most summary fashion, of his 
explorations is obviously impossible within the space at our 
disposal. But we must coincide with the general opinion that, 
considering how late in life his geological career began, and under 
what unfavourable circumstances he worked, his results are truly 
marvellous, both in their extent and their value. What might 
he not have accomplished had he not wasted some fourteen of 
the best years of his life in his uncle’s counting-house ! 
His labours in exploration were twice interrupted by exhibi- 
tions. For the London Exhibition of 1851 he had prepared a 
very important collection of the economic minerals of Canada, 
and he was appointed a juror in the Mineralogical and Metallur- 
gical department. On this occasion he was elected a Fellow of 
the Royal Society. Dr. Harrington somewhat drily remarks 
that leave of absence had been, indeed, given to Logan that he 
might attend the Exhibition, but that “he was allowed the 
privilege of paying all his own expenses.” 
In 1855, he had again to prepare for the Paris Exhibition, 
which he attended as “ Special Commissioner.” He received a 
Grand Gold Medal of Honour for his maps and minerals, and 
was made a Chevalier of the Legion of Honour. In addition, 
Dr. Barrington informs us that a “ greater distinction awaited 
him at the hands of his own Sovereign.” This was simply the 
rank of knighthood, which, considering the class of men upon 
whom it is often conferred, is no very dazzling honour. The 
Geological Society awarded him about the same time the 
Wollaston Medal. One of the Royal Gold Medals was subse- 
quently conferred upon him by the Council of the Royal Society, 
and in 1867, the Emperor of the French raised him to the rank 
of Officer of the Legion of Honour. In 1869, though he had 
hoped for the time when his explorations should extend from the 
Atlantic to the Pacific, advancing age compelled him to tender 
his resignation. In 1874, he crossed the Atlantic for the last 
time, and on June 22, 1875, he died at Castle Llechryd, in Wales. 
Of chemistry, mineralogy, and palaeontology Logan had but 
a limited knowledge. His strength was in stratigraphy. But 
he was always ready to avail himself of the services of others in 
those departments where he was deficient, and to give them 
due credit. Dr. T. S. Hunt, who has since earned so high a 
reputation, became chemist and mineralogist to the Survey in 
1846. As a theorist, Logan never attempted to distinguish
