The architect had .much choice or variety of work in those* 

 days. 



The bridge over the Rbone at Avignon, in southern France., 

 built in 1200 a.d., with arches up to 80-feet span, was classed as 

 a work of architecture In those days the architect was what the 

 derivation of the name indicates — the master-builder — and he 

 turned his hand to a great variety of work. 



In the fifteenth century the distinction between architectural 

 and engineering woTk was recognised, for the great artist 

 Leonardo da Vinci, best known by his paintings, also gained fame 

 a^ a military engineer and an engineer for hydraulic and irriga- 

 tion works, and styled himself both engineer and architect. He 

 was also a leader in science. 



In the same century the great Michael Angeloi was the architect 

 of St. Peter's at Rome and engineer for the fortifications at Rome. 



One hundred years ago the engineers began to define two 

 branches of their work, viz., military and civil engineering. Now 

 we have, in addition, mechanical, electrical, hydraulic, mining, 

 metallurgical, sanitary, and other branches. In America valua- 

 tion engineers are recognised as a class by themselves. 



But the work of all these overlaps, and they are all engineers. 

 The work of the architect, too, is tending to specialization. 

 There is an interesting survival of old terminology in the pre- 

 sent-day term of "naval architect," while different members of 

 the profession follow up different^ branches of architectural work. 

 Again, much building construction is the joint work of architects 

 and engineers, such as steel-framed structures and reinforced con- 

 crete buildings. 



Professions so closely allied and brought together should walk 

 hand in hand, as we are doing here, without rivalry beyond what 

 is healthy and helpful to both. We have a good example to 

 follow if we look at the friendly relations of doctors, surgeons, 

 and medical specialists, and of the different branches of the legal 

 profession. 



We are met here tO' promote the advancement of science. Let 

 u's think of a few ways in which we may be able to bring benefit 

 to our own professions in doing so. It is up to us to practise 

 what we preach, and, if we believe in science and its value to 

 mankind, to put it into practical application to our work. 



This is a utilitarian age. While the leaders in scientific work 

 and research are going forward and making wonderful advances 

 in knowledge, the full benefit of this increased knowledge will 

 not be obtained unless others use and apply it to benefit man- 

 kind in their work, and it is in this way that most of us are 

 called upon to to do our duty. Our opportunities are great, and
