The Foreign Office has just issued a series of ‘ Reports received 
from Her Majesty’s Secretaries of Embassy and Legation respecting 
Coal.’ These Reports originated in a circular issued in 1865 by 
Earl Russell, and sent to all countries producing coal, or with 
whom England had any trade for coal, requiring— 
1. A statement of the coal-fields actually worked, and the 
development in production. 
2. A statement of the external trade of each country in coal. 
3. The ratio in which each country draws its supplies from 
Great Britain. 
Reports from twenty-eight countries have been furnished. An 
Appendix gives ‘ Extracts from Commercial Reports by Her Majesty’s 
Consuls ;’ these are short, but nevertheless valuable notes respecting 
twenty-two places in various parts of the world producing coal or 
receiving British coal. 
Such returns should possess considerable value. Unfortunately, 
the questions were committed to the care of a class of men, who, 
from their training, are entirely unfitted to answer them with any 
approach to correctness. The Secretaries of Embassy and Legation 
haye never before been taxed with an inquiry such as this. They 
have consequently taken such information as came to their hands, 
and it is evident that they have not often troubled themselves to 
obtain the most recent. Austria, Prussia, and Belgium, for example, 
publish annually very complete returns of the mineral productions 
of each country. The returns for 1864 were very readily obtain- 
able, yet 1862 is regarded as the most recent returns by the 
reporters. The American Government have lately published a 
valuable return, from which we have quoted; but the return of 
Mr. Burnley is almost entirely derived from Taylor’s ‘ Statistics of 
Coal,’ the latest edition of which was published in 1855, and that 
edition was little more than a reprint of a very much older book,
