=Aim and Object of the Company.=—When the Pneumatic Transit Company was formed, it was the aim and object of its promoters to construct an extensive system of underground tubes in the City of Philadelphia which would serve, first, for the rapid transmission of mail, second, for the quick delivery of merchandise from the large retail stores, third, for the transmission of telegrams or messages within the city limits, and, fourth, to conduct a general local express business with greater speed than can be done in any other manner. To accomplish this result sub-stations were to be located six or eight blocks apart throughout a large portion of the city, and a central station was to be established in the centre of the business section. Stations were also to be established in the more important retail stores and large office buildings, and all of the stations were to be connected by tubes forming one large system. For the transmission of mail it was planned to connect the main post-office with the sub-post-offices by tubes of a size large enough to carry all of the first-class and most of the other classes of mail matter. The sub-post-offices would be divided into groups, all of the offices in one group being connected to the same line, which would terminate at the main post-office. Most of the business would be between the main and individual sub-offices; in addition to this there would be some local mail sent between the sub-offices which, for offices in the same group, could be despatched directly without passing through the main office. The advantages to be gained by the use of these tubes over the present wagon service are very apparent. It places all the sub-post-offices in almost instant communication with the main office and with each other. It was a part of the general plan to lay tubes from the main post-office to the railway stations, thereby hastening the despatch and receipt of mails to and from the trains. It was expected that the bulk of the business would consist in the delivery of parcels from the retail stores to the private houses in the residence sections of the city. Of course it would not be practicable to lay a tube to each house, but with a station not more than four or five blocks away, the parcels would be sent through the tube to the nearest station, and then delivered by messengers to the houses with a minimum loss of time. Ladies could do their shopping and find their purchases at home when they returned.
