the Ordnance Map of Scotland. 351 



But although the whole Map of France is comprised in 208 sheets, 

 yet the necessity for a smaller map has been so urgently felt by the 

 country, that the Government has been for some time engaged in 

 preparing a reduction of the great map, to one-fourth the scale, or 

 five miles to one inch. 



This course has also been followed in Austrian Italy, a reduction 

 of the original map to a scale of four and one-half miles to one inch 

 having been recently published. The Survey of Switzerland, lately 

 commenced, is published on a scale of only five-eighths of an inch 

 to a mile. 



Besides the considerations already advanced, the question of ex- 

 pense is materially affected by the scale." In the estimates for sur- 

 veying and engraving the Ordnance Map of Lancashire,* the total 

 cost on the one-inch scale is stated at £12,058, and on the six-inch 

 scale £49,267, or more than four times the amount. The former 

 is for a finished map with the hills shaded, and the latter for an out- 

 line with contours ; the comparative cost of engraving alone, is, 

 for the one-inch scale £2378, and for the six-inch scale £4515 ; 

 frcJm this it may be safely concluded, that the map on the one-inch 

 scale would be less expensive by at least one-half, or the saving on 

 Scotland would be about £400,000.
