Rejection of moderate drinkers by business houses is not done on moral grounds alone, but because experience has proved the danger of employing men who have not their faculties fully under control _all_ the time they are at work. The rules are especially strict for men working for a railroad or street railway company. The Pennsylvania Railroad Company replied to my inquiry as to their custom of discriminating against drinking men in these words: "We have no printed rules in regard to this except in a general way,--that no employee is allowed to go into a saloon during his hours of work or wearing the company's uniform. Of course the men are promptly discharged or disciplined if they show the effects of liquor while on duty, and the whole tendency of the administration of the rules is to get rid of any men who are habitual drinkers, but the administration of the rules and discipline is left to the superintendent of each division." The Interborough Rapid Transit Company of New York has these printed rules for the physical standard required for applicants for employment: 1. _Examination of heart and arteries._ Rejection of candidates showing excessive or long-continued use of tobacco and alcohol, with explanation of condition, causes, and dangers of continued use. Warning to chiefs of departments regarding those accepted who show tendency to drink at times, but whose physical examination does not disclose sufficient evidence to warrant their disqualifications. Foremen and chiefs of departments to be notified and to carry out the policy of employing only men who are at all times sober and not under the influence of alcohol at all. 2. _On reexamination of employees._ Warning to or rejection of those showing, on physical examination, indulgence to excess of alcohol, tobacco, or drugs. Warning to chief of department of evidence of such habits on part of any employee examined for any reason, but retained in service of the company with injunction to chief of department to speak with such employee and have him under proper supervision.
