cent, of metal. Since 1825 the total production of tin through- 

 out the world has increased more than three fold, and last year 

 it seems to have been about as follows : —

The great improvements in mining during the last quarter 

 of a century have been the introduction of wire-ropes, the use 

 of the skip in hauling, the improvements in dressing ; more 

 especially the adoption of the Brompton calciner, and the boring 

 machines, whilst the use of dynamite, in some mines, has been 

 of great value. There can be no doubt that from improved 

 ventilation, greatly due, I believe, to Mr. Teague, the health of 

 our miners has suffered less than formerly. These practical 

 details come, perhaps, rather within the scope of the sister 

 societies, but it is strictly within the province marked out for 

 itself by this Institution, to honour those among the sons of 

 Coinwall whose energy and talents have contributed, by their 

 inventions, to the benefit of their fellows, and when we think of 

 what we owe to those who led the way in the development of 

 steam machinery, we cannot but rejoice to know that the ser- 

 vices of a great Cornish engineer are at length being recognized, 

 not only in Cornwall, but throughout England. It would be 

 impossible for me to attempt to recapitulate the midtifarious 

 inventions which the ingenious and daring spirit of Richard 

 Trevithick produced, or prepared for others to complete. A 

 summary of them would fill a volume, but you know he was not 

 a man to create a fortune or to win friends, and that he died 

 penniless and alone. But I am glad to say, his memory is to be 

 perpetuated, and the proposal is that the subscriptions received 

 towards the memorial should be utilized by placing a Bust (if 

 possible), in Westminster Abbey, and establishing scholarships 

 bearing his name, to aid in the technical education of young 

 men for the profession of mining and other engineers. 



But Trevithick is not the only Cornish inventor who has 

 not received the recognition which his merits deserved. Sir
