The postal car is of a peculiar form of construction, and will be run with a tender. The tender will be a simple express‑car arranged for merely carrying through‑mails. The postal‑car proper is of ordinary width, but longer than usual having a length of 60 feet. It is built of white pine wood, and painted white inside and out. Internally the car is divided into three compartments. The first of these contains 975 Pigeon‑holes, each of them representing a station. A shelf surrounding the holes is used for the purpose of sorting the letters. Letter‑drops, with their apertures to the outside of the car, are in this compartment, and may be used by persons just as the ordinary drops are. The next compartment of the car is fitted up with boxes and hooks for the reception of mail‑bags and newspapers destined for way‑stations. Behind this, and in the last compartment, are a number of boxes arranged in rows. One side of these boxes is open, while the opposite side is closed by a door on hinges. From hooks in these boxes.the mailbags are suspended, and the newspapers as fast as sorted are thrown through the boxes into the bags, each of which represents a station. Four of these postal‑cars, with tenders, will be put on the line. At present, however, only three are built, and these were constructed within thirteen days after notice was received by the railroad officials to prepare the cars. The cars are well heated and lighted, and have the recently invented appliances for keeping out sparks of the fire from the locomotive, and for catching mailbags at stations, etc.
