I was dressed in my one white linen shirt, which was usually kept sacred for the Sabbath day, my blue round-about, and my whole Sunday suit.  I had at that time, and for a few weeks after I entered the telegraph service, but one linen suit of summer clothing; and every Saturday night, no matter if that was my night on duty and I did not return till near midnight, my mother washed those clothes and ironed them, and I put them on fresh on Sabbath morning.  There was nothing that heroine did not do in the struggle we were making for elbow room in the western world.  Father’s long factory hours tried his strength, but he, too, fought the good fight like a hero and never failed to encourage me.

The interview was successful.  I took care to explain that I did not know Pittsburgh, that perhaps I would not do, would not be strong enough; but all I wanted was a trial.  He asked me how soon I could come, and I said that I could stay now if wanted.  And, looking back over the circumstance, I think that answer might well be pondered by young men.  It is a great mistake not to seize the opportunity.  The position was offered to me; something might occur, some other boy might be sent for.  Having got myself in I proposed to stay there if I could.  Mr. Brooks very kindly called the other boy—­for it was an additional messenger that was wanted—­and asked him to show me about, and let me go with him and learn the business.  I soon found opportunity to run down to the corner of the street and tell my father that it was all right, and to go home and tell mother that I had got the situation.

And that is how in 1850 I got my first real start in life.  From the dark cellar running a steam-engine at two dollars a week, begrimed with coal dirt, without a trace of the elevating influences of life, I was lifted into paradise, yes, heaven, as it seemed to me, with newspapers, pens, pencils, and sunshine about me.  There was scarcely a minute in which I could not learn something or find out how much there was to learn and how little I knew.  I felt that my foot was upon the ladder and that I was bound to climb.

I had only one fear, and that was that I could not learn quickly enough the addresses of the various business houses to which messages had to be delivered.  I therefore began to note the signs of these houses up one side of the street and down the other.  At night I exercised my memory by naming in succession the various firms.  Before long I could shut my eyes and, beginning at the foot of a business street, call off the names of the firms in proper order along one side to the top of the street, then crossing on the other side go down in regular order to the foot again.

The next step was to know the men themselves, for it gave a messenger a great advantage, and often saved a long journey, if he knew members or employees of firms.  He might meet one of these going direct to his office.  It was reckoned a great triumph among the boys to deliver a message upon the street.  And there was the additional satisfaction to the boy himself, that a great man (and most men are great to messengers), stopped upon the street in this way, seldom failed to note the boy and compliment him.
