I was quite unable to make any white metal alloy hard enough to be made into powder by my machinery.
It is true I had been successful on a small scale in overcoming one of the main difficulties in the new process, but there was still much to invent, and much that at that period I necessarily knew nothing about.
We fixed on No. 4, Queen Street Place, for our City offices, and it was from there that so many of my patented inventions were dated.
At this period the enthusiasm of the amateur was fast giving way to a more steady commercial instinct, and I let no opportunity slip of improving my position, but I felt that I was still labouring under the disadvantage of not having acquired some technical profession.
In such a case secrecy must be absolute to be effective, and although mere vague curiosity induced many persons of my intimate acquaintance to ask to be allowed to just go in and have a peep, I never admitted anyone.
The bronze powder business, however, no longer required my personal attention, and was well managed by those I had chosen as the guardians of a secret, which was long and honourably kept.
