mic specimens conspicuously forward; and it appears to me that in the 
exhibition of these, large masses will make a greater impression on the mind 
than small specimens This induces me to say that I should 
like you to send to Montreal, as soon as it can be done by water communi- 
cation in the spring, a thundering piece of gypsum. Let it be as white 
as possible If you come across the lithographic stone, let 
us have a huge slab of it, 6 or 8 inches thick.” 
About the same time he wrote to De la Beche, Director of the Geolo- 
gical Survey of Great Britain: “I have hired a house on speculation and 
am ordering proper cases to hold some of them” (specimens collected by 
himself and Murray), “in the confident expectation that the expenditure 
will be sanctioned by the Legislature. But perhaps I may be reckoning 
without my host, and may be left in the lurch after all.” The house 
referred to, which served as museum, office, and laboratory was No. 40, 
Great St. James street. 
All Logan’s courage, sagacity, and indifference to personal material 
gain were needed to keep his Survey going for the next few years. By 
the end of 1844 all of the fifteen hundred pounds was gone and eight hundred 
more out of his own pocket. However, he was asked by the Government 
to prepare an estimate of the cost of continuing the Survey, which he did 
with great care, taking pains also to explain his work and aims to the 
members of the Legislature. His bill was enacted early in 1845, providing 
£2,000 annually for five years. Three hundred of this went to Murray 
for salary, an equal amount to a Polish chemist and mineralogist, De- 
Rottermund, whom Logan had engaged in 1844 on his own responsibility, 
and one hundred and twenty for rental of their quarters; and Logan 
recovered his eight hundred pounds. This act of 1845 contained the first 
official authorization of museum work, for it provided that the Geological 
Survey should “furnish a full and scientific description of its Rocks, Soils, 
and Minerals together with a collection of Specimens to 
illustrate the same.” 
During 1846 the museum and officers were moved to a more commo- 
dious building on Little St. James street, which was leased from the Natural 
History Society. The arrangement appears to have been mutually bene- 
ficial, for the Society retained rooms on the third floor for its specimens 
and books. 
The government had been moved from Montreal to Toronto, and in 
February, 1850, Logan was there, once more striving for support to have 
the Act to provide support for the Geological Survey renewed. After some 
delay this was done, and the same annual supply of money was promised 
for another five years. 
It was also decided at this time that a collection of Canadian economic 
minerals should be sent to the great 1851 Exhibition in London, and the 
preparation of the collection was entrusted to Logan and his staff. This 
was a new museum activity, the first of a long series of exhibitions of 
Canadian minerals and mineral products at World’s fairs and similar 
international exhibitions, that continued until 1921, when it was finally 
taken over by a special organization now in the Department of Trade and 
Commerce, called the Exhibitions Commission, that had been created 
some years before. Logan performed this task so thoroughly that special 
commendation was given the Canadian exhibit in the report of the Exhibi- 
tion Committee: “Before commencing the detailed description of objects
