It must not be supposed that everything has been left until the last moment, and that the mail matter has been tumbled into the cars on the eve of departure, to be handled as best it may in the short run to Albany; for under such conditions the task would be an impossibility even to an army of trained hands. Work has been in progress since four o'clock in the afternoon, and it has been steady, hard labor every minute of the time. The five cars have been backed down to the tracks opposite Forty-fifth Street, and have been so placed that they are convenient of access to the big lumbering mail wagons which are familiar sights in the streets of the metropolis. The crew of nineteen men, skilled in the handling of mail matter, and thorough experts in the geography of the country, reported to the chief clerk and took up their stations in the various cars at the hour named. At the same time the wagons began arriving from the General Post-Office with their tons of matter which had "originated" in New York, and were soon transferring their loads to the cars, where agile hands were in waiting to receive them. Since the removal of the deadly stoves from the railway trains the occupants of the postal cars have suffered to no small extent owing to the lack of heat. These cars are provided with steam-heating apparatus which is worked from the engine, but they are occupied for five hours before the engine comes near them, and in cold weather the hands of the men employed in distributing letters become numb with cold. This is a matter which should receive prompt attention. [Illustration: At the Last Moment.]
