editor's preface. 



Professor Grenville Cole's Open Air Studies in Geology ; Messrs. GUY AND 

 Co., of Limerick and Cork, and the publishers of the Irish Naturalist. 

 Miss Mitchell has prepared the Index. 



Messrs. Browne and Nolan, Limited, of Nassau-street, have printed 

 and published this revised edition in accordance with the terms of a special 

 agreement with the Department of Agriculture and Technical Instruction 

 for Ireland. Its Typographical and other merits — the work is printed on a 

 specially made Irish paper — are the best evidence of the care and taste 

 which that firm have brought to the enterprise. In the literary preparation 

 of the volume, and in the arduous work of proof reading, Mr. THOMAS 

 Butler, a Staff Officer in the Statistics and Intelligence Branch, and 

 Messrs. Walier E. C ALLAN (who is a joint author of the important article 

 on " The Brewing Industry "), and Ernest A. MORRIS, two other members 

 of my staff, have given me valuable assistance. It is unnecessary to add 

 that without the unstinted and invaluable aid of my colleagues in the 

 Department, and the other contributors, this work would not have been 

 possible. 



WILLIAM P. COYNE.
