The following is from a letter by Mr. Robinson to his brother on October 25, 1873:
"Mr. Baldwin could not say enough in favor of the signals." * * * "Of course I remained in the background, except, as to giving explanations. After a while Cassatt, Pitcairn and Thomson got into a discussion of the battery and other points, and called me into the ring to enter into the discussion, and it was quite animated for some time. Pitcairn proceeded to give his idea of what a signal should be, and Mr. Baldwin and the rest proceeded to show him that this, was exactly his ideal."
"Mr. Gardner, after learning modus operandi from diagrams &c. proceeded to lay down the law to the rest, demonstrating how they would have 'prevented those accidents.'"
"They were all very much pleased with the signals but their operation seemed such a surprise that I judge it will take them several days to think over and realize the actual operation and importance of the thing."
Robinson's Work in New England
In December, 1875, Mr. Robinson went to Boston and took up his residence there.
In January, 1876, he made an installation of his closed rail circuit system between Elm street and North avenue, West Somerville, on a branch of the Boston and Lowell railroad. This installation worked perfectly from the beginning.
The Emperor of Brazil Examines the Robinson Signal System
In June, 1876, His Imperial Majesty, Dom Pedro II, Emperor of Brazil, being then in Boston, graciously accepted an invitation from Mr. Robinson to examine his Wireless Signal System in operation on the Boston & Lowell railroad. Accordingly, on June 14, they proceeded together by special train to West Somerville for the purpose.
The following is an account of the visit, from the Boston Post of June 15, 1876:
