364 Geological Survey of Great Britain. 



vey of ISTova Scotia. I recommended the gentleman to come and 

 consult Sir William Logan, as no man was better acquainted with 

 the necessities of a Colonial Survey than he. I firmly believe that 

 the time will come when the authorities not only of Canada and 

 the United States but of every civilized country, will find it to be 

 of the greatest benefit to have not only topographical maps of 

 every part of the country, with all their features delineated in the 

 most accurate manner, but also upon these to have every Geologi- 

 cal feature surveyed to the most minute detail, and published at 

 the expense of Government. Our Government is so completely 

 aware of this, and the people of Great Britain are so confident of 

 its advantages that it would never occur to any one to think of 

 stopping the survey of Great Britain from any motive whatever. 

 You will have an idea of the value set upon our labours by the 

 public when I tell you that 5000 sheets of these expensive maps 

 and sections are annually sold in Great Britain. They are pub" 

 lished bythe Station aryOflice, and are sold through Longman & Co. 

 The profit, if there is any, goes to the Stationary Ofiice, but their 

 object is to sell them as cheap as possible, without any reference 

 to money returns. Coloured maps such as these (pointing to those 

 hanging up) are sold from 2s 6d to 8s. according to the amount 

 of work in them ; the sectional sheets are 5s each. We are now 

 well aware in Britain that the importance of our country in the 

 scale of nations depends upon its mineral wealth. Government, 

 therefore, freely grants whatever is considered essential to the 

 Survey. We have as many men upon the Survey at present as 

 we can use. But if we found it necessary to double the number 

 and to ask for increased grants, I fully believe it would be freely 

 given. We have published about 50 sheets of maps, embracing 

 an extent of about 36,000 square miles. About 50 horizontal sec- 

 tions of the country illustrate these maps, and about 20 sheets of 

 vertical sections of the coal measures are already given, and we 

 intend to proceed in the same way with the rest of the country 

 I ought to have mentioned that two years ago Sir Henry de la Beche 

 worn out in body and mind gradually sank and died, regretted 

 by all his friends, men of science, and especially by those to whom 

 .he had long endeared himself, who were connected with him in 

 an official capacity. He was succeeded by Sir Roderick Murchison, 

 a gentleman whose previous geological labors and great skill iii 

 the field .fitted him more thoroughly than any other person to 

 succeed Sir Henry del a Beche, whose monument it is to have estab-
