first great exposition—­opened within a month after the completion of the first telephone.  The public knew nothing of the telephone, and before it could be made a commercial success and placed in general service the interest of investors and possible users had to be aroused.  The Centennial seemed to offer an unusual opportunity to place the telephone before the public.  But Bell, like Morse, had no money with which to push his invention.  Hubbard was one of the commissioners of the exposition, and exerted his influence sufficiently so that a small table was placed in an odd corner in the Department of Education for the exhibition of the apparatus.  The space assigned was a narrow strip between the stairway and the wall.

But no provision was made to allow Bell himself to be present.  The young inventor was almost entirely without funds.  Sanders and Hubbard had paid nothing but his room rent and the cost of his experiments.  He had devoted himself to his inventions so entirely that he had lost all of his professional income.  So it was that he was forced to face the prospect of staying in Boston and allowing this opportunity of opportunities to pass unimproved.  His fiancee, Miss Hubbard, expected to attend the exposition, and had heard nothing of Bell’s inability to go.  He went with her to the station, and as the train was leaving she learned for the first time that he was not to accompany her.  She burst into tears at the disappointment.  Seeing this, Bell dashed madly after the train and succeeded in boarding it.  Without money or baggage, he nevertheless succeeded in arriving in Philadelphia.

Bell arrived at the exposition but a few days before the judges were to make their tour of inspection.  With considerable difficulty Hubbard had secured their promise that they would stop and examine the telephone.  They seemed to regard it as a toy not worth their attention, and the public generally had displayed no interest in the device.  When the day for the inspection arrived Bell waited eagerly.  As the day passed his hope began to fall, as there seemed little possibility that the judges would reach his exhibit.  The Western Union’s exhibit of recording telegraphs, the self-binding harvester, the first electric light, Gray’s musical telegraph, and other prominently displayed wonders had occupied the attention of the scientists.  It was well past supper-time when they came to Bell’s table behind the stairs, and most of the judges were tired out and loudly announced their intention of quitting then and there.

At this critical moment, while they were fingering Bell’s apparatus indifferently and preparing for their departure, a strange and fortunate thing occurred.  Followed by a group of brilliantly attired courtiers, the Emperor of Brazil appeared.  He rushed up to Bell and greeted him with a warmth of affection that electrified the indifferent judges.  They watched the scene in astonishment, wondering who this young Bell was that he could attract the attention
