those who wasted it, would have paid for the whole Survey and 

 Museum since its establishment, and given it an endowment of 

 £2000 per annum for ever." (p. 469). 



The appointment of Dr. Oldham to the Directorship of the Indian 

 Geological Survey, in November, 1850, rendered vacant the post of 

 Director of the Irish branch of the Geological Survey, which was 

 offered to Mr. Jukes, and undertaken by him early in 1851. From 

 this date to his death, on 29th July, 1869, he worked, if possible, 

 harder than before ; but we are inclined to believe that his was a 

 mind and body constituted for active mental and physical exercise. 

 What really operated unfavourably upon him may be termed the 

 official worry and the constant sense of responsibility in which his 

 new duties involved him. Heretofore he had been a "private" in 

 the ranks of the English Survey, working indeed both with head and 

 hands ; but now that he was suddenly raised to the rank of a Director 

 (with the Professorship of Geology in the Eoyal College of Science 

 in Dublin, added thei'eto in 1854), the light-heartedness which could 

 laugh at difficulties gradually faded away. Like the late Prof. 

 Edward Forbes, he chafed under official restraint, and doubtless was 

 Teady to exclaim with his beloved friend, 



" Oh, the red-tape worm is gnawing my soul." 

 Work, however, went on with a will ; for, although his staff of assis- 

 tants was small, he completed the survey of about one-half the super- 

 ficial area of Ireland, together with the editing and partial authorship 

 of about forty-two explanatory Memoirs on the Geology of the country.^ 



Nor were his labours confined to his official work ; for in the list 

 of 77 Books, Eeports, Articles, and papers, given at the end of this 

 volume, 53 were published between 1850 and 1868 ; the last paper 

 he wrote being that on "the Chalk of Antrim," which appeared 

 in the Geological Magazine, Vol. Y., 1868, p. 345. Nearly all his 

 spare time, from 1864 to 1868, was devoted to an examination and 

 comparison of the Devonian Eocks of the South of Ireland with 

 those of Devon and Somerset and of Ehenish Prussia. Several 

 papers relating to this much- vexed question were communicated by 

 Prof. Jukes to the Eoyal Geological Society of Ireland; to the 

 Geological Society of London ; and the Geological Magazine, 

 1866, Vol. IV., p. 87. Had Mr. Jukes's life been spared, he would 

 probably have more fully worked out his views ; this much, how- 

 ever, must be said, in justice to Mr. Jukes, that the result of his 

 researches and papers has led to an entire and careful re -examination 

 of the country under dispute ; and only on the evening of 22nd of 

 November, in the course of debate on a paper, read before the 

 Geological Society of London, Mr. Godwin-Austen expressed his 

 conviction that we should live to see the term " Devonian" abolished 

 from the series of formations ! there being no true separation 

 between the Devonian and Carboniferous series. 



The most highly valued of all Professor Jukes's publications is 



doubtless his " Manual of Geology," the third edition of which has
