ENGINEERING SCIENCE BEFORE, DUR- 

 ING AND AFTER THE WARi 



Three years of anxiety and stress have 

 passed since the last meeting of the British 

 Association. The weight of the struggle 

 which pressed heavily upon us at the time 

 of the Newcastle meeting in 1916 had in- 

 cx'eased so much in intensity by the spring 

 of 1917 that the council, after consultation 

 with the local committee at Bournemouth, 

 finally decided to cancel the summer meet- 

 ing of that year. This was the first time in 

 the history of the association that an an- 

 nual meeting was not held. 



We all rejoice to feel that the terrible 

 ordeal through which the whole empire has 

 been passing has now reached its final 

 phases, and that during the period of re- 

 organization, social and industrial, it is pos- 

 sible to resume the annual meetings of the 

 association under happier conditions. "We 

 have gladly and with much appreciation 

 accepted the renewed invitation of our 

 friends and colleagues at Bournemouth. 



We are gathered together at a time when, 

 after a great upheaval, the elemental con- 

 ditions of organization of the world are 

 still in flux, and we have to consider how 

 to influence and mould the recrystallization 

 of these elements into the best forms and 

 most economic rearrangements fox the 

 benefit of civilization. That the British 

 Association is capable of exerting a great 

 influence in guiding the nation towards ad- 

 vancement in the sciences and arts in the 

 most general sense there can be no ques-
