ROUND ABOUT I.AKK BKI^FAST.^ 



BY R. I.I.OYD PRAKGKR. 



The second map of the Drift Survey of Ireland has been 

 published; and with it a new descriptive Memoir, dealing with 

 both the solid and surface geolog^^ In the case of the Dublin 

 map, issued last year, that city lay well in the middle of one of 

 the sheets of the one-inch ordnance map (sheet 112), and the 

 edges of the sheet provided convenient boundaries for the 

 field-work. Here, on the other hand^ the city of Belfast lies 

 close to the intersection of the edges of four sheets, con- 

 sequently a map has been adopted of the usual size of a one- 

 inch sheet, but having Belfast placed nearly centrally upon it. 

 The area thus included extends roughly from lyisburn to 

 Bangor, and from Ardmillan to Clad^^ Thus about two-thirds 

 of the map belongs to Down, one-third to Antrim. The map 

 is excellently turned out, and with the marvellously accurate 

 register for which the Southampton office is justly noted. We 

 at once notice a difference in the colour-printing as compared 

 with the Dublin map. The latter was printed at the Dublin 

 Ordnance Survey office by the three-colour process, whereas 

 in this Southampton-printed sheet the old separate-colour 

 process of chromo-lithograph}" has been reverted to, requiring 

 no less than nineteen consecutive printings. While admiring 

 the beauty and effectiveness of the map, we feel a lingering 

 regret that it is not, like its predecessor, '* made in Ireland." 

 The scheme of colours is similar to, but not identical with, 

 that which has been used on the maps of the Knglish Drift 

 Survey, a series of strong colours being used for the solid
