including mathematicians, chemists, electricians, secretary, bookkeeper, and mechanics, were paid a salary. They were devoted to Edison, who, though he worked them hard at times, was an indulgent master, and sometimes joined them in a general holiday. All of them spoke in the highest terms of the inventor and the man.
The Menlo establishment was unique in the world. It was founded for the sole purpose of applying the properties of matter to the production of new inventions. For love of science or the hope of gain, men had experimented before, and worked out their inventions in the laboratories of colleges and manufactories. But Edison seems to have been the first to organise a staff of trained assistants to hunt up useful facts in books, old and modern, and discover fresh ones by experiment, in order to develop his ideas or suggest new ones, together with skilled workmen to embody them in the fittest manner; and all with the avowed object of taking out patents, and introducing the novel apparatus as a commercial speculation. He did not manufacture his machines for sale; he simply created the models, and left their multiplication to other people. There are different ways of looking at Nature:
'To some she is the goddess great;
To some the milch-cow of the field;
Their business is to calculate
The butter she will yield.'
The institution has proved a remarkable success. From it has emanated a series of marvellous inventions which have carried the name of Edison throughout the whole civilised world. Expense was disregarded in making the laboratory as efficient as possible; the very best equipment was provided, the ablest assistants employed, and the profit has been immense. Edison
