an examiner.
2. Each examiner shall be provided with:—
(a) A set of Snellen's test types with at least three
cards of each size of letters shown in different combinations (a single fine on each card) for testing acute-
ness of vision.
(6) An American Railway Association standard

3. Examinations shall be conducted in a well-lighted
room or car in which a distance of twenty feet can be
measured from test type, or face of lantern, to candidate;
shades or curtains shall be provided in order to darken
room or car, for lantern test.
4. In testing vision, colour perception, and hearing,
only those concerned in such test other than the examiner
and candidate shall be permitted to be present.
5. (a) The result of each examination must be shown
in duplicate on the prescribed form, one copy to be pre- served for reference by the examiners, the other to be forwarded to the division superintendent for inspection
record and file. k {
(b) Those charged with the duty of making examinations on each division must keep proper check to
ensure re-examination of all employees when due, and
must see that all employees who should be examined
by an expert oculist under the rules, are required to
take such examinations promptly, and that all glasses
to be used by employees are sent to the oculist for
approval as per Rule 13.
(c) Examiners will issue to each person who passes

all cases wherein an employee should be
examined by committee, or appears to be disqualified,
giving full information as to result of examination.
(e) Oculists or experts will report result of their

6. All persons desiring to enter the service (applicants)
must take entrance examination without the use of glasses
for distant vision, excepting Class E.
7. Applicants for entrance to service as enginemen, firemen, trainmen or brakemen, shall not be accepted if they
have to use glasses for near vision. Applicants for other
positions and employees in all branches of the service may
use glasses for near vision when undergoing examination.
8. When the distant vision of an employee can be improved by the aid of glasses he should wear them.
9. All employees who require the aid of glasses for
distant vision must wear them at all times when on duty
and must carry a duplicate pair for use in emergency and
will be examined with each pair.
10. All employees excepting those indoors who are
permitted to wear glasses for distant vision while on duty

against temporary fire blindness shall be permitted and
should be encouraged.
13. Glasses of all kinds must be approved by an oculist
designated by the company.
14. Applicants having a squint, or who are cross-eyed
shall not be accepted. Examiners who suspect a case of
double vision should use some simple test to determine its
presence.
15. Enginemen who have less than 20-30 vision in either
eye, without glasses, must be examined by a qualified
oculist designated by the company.
16. Enginemen in Class A who fail to reach required
standard must be examined by a committee of two appointed by the* and upon recommendation
of this committee they may be permitted to wear glasses
provided their combined vision can be brought to 20-20;
committee to recommend the service to which they may

another, or being promoted, must pass entrance examination of class they desire to enter except that those who
have been injured in service, or who have been in continuous service for at least two years, may be transferred to
*To be filled in by each road to suit its own requirments. positions of hostlers, switch tenders, and crossing flagmen;
also from one position to another under Class E upon
passing the respective re-examination standards.
20. An employee in Class C, D, E, or F who has been in
continuous service for a period of not less than fifteen
years, and who, through diminution of vision or muscular
imbalance, fails to reach required standard will be considered satisfactory if his acuteness of vision, with or
without glasses, reaches the maximum, standard specified
for the class of service in which he is employed.
21. The test type should be in good fight, the bottom of
the card about on a level with the eye. Place the candidate
twenty feet from the card, and ask him to read the type
with both eyes open, then cover one of his eyes with a
card, or shade, held firmly against the nose, taking care
not to let it press against the eye ball, and instruct him to
read with the other eye such type as may be indicated.
Each eye shall be tested separately.
(a) Examiners are reminded that the normal-
eyed should read the twenty-foot (or 6 meter) letters
at 20 feet, in which case the visual power should be
expressed by the fraction 20-20. Should a candidate
be unable to read the twenty-foot letters, at 20 feet
but be able to read the 30 foot letters the result should
be indicated by the fraction 20-30. If he can only
read the forty-foot letters record should be 20-40, &c.

eighteen inches to pass the test. Further tests should
be made by having the candidate read written train
orders.
22. Applicants for entrance to service in Classes A and
C will undergo additional test to ascertain if far-sighted to
the extent of two diopters. Examiners will use combinations in trial frames representing plane and convex lenses,
varying the test so that the candidate's former experience
or knowledge obtained from others may be valueless. If
an applicant reads without difficulty the twenty-foot
letters at 20 feet through convex lenses of 2D he will not
be considered satisfactory.
23. Examiners shall adhere to instructions laid down by
Holmgren or Thompson in using colour-selection test and shall examine the colour sense of each eye separately.
Further examination shall be made with Williams lantern
or one similarly constructed in the manner specified by
Dr. Williams.
24. No applicant shall be accepted into the service and
no employee retained in any of the classes specified in
following standards who has defective colour sense.
25. No employee shall be disqualified from service by
reason of defective colour sense without an examination
by an oculist designated by the company.
26. In examination of hearing (which shall be with human voice), each ear shall be tested separately and the
candidate should not see the movement of the examiners'
lips.
27. Applicants for entrance to service must be able to
hear and repeat an ordinary conversation or names and
numbers spoken in a conversational tone, at a distance of
20 feet, in which case the hearing should be expressed by
the fraction 20-20. When conversation can be heard
at only ten feet, the hearing should be expressed bv the
fraction 10-20.
28. Employees will not be retained in the service if
hearing is less than 15-20 in one ear, and 5-20 in the other;
or less than 10-20 in each ear.
29. Employees included in the standards^of vision must
be re-examined as follows:—
(a) All classes every two years.
(6) Employees in engine, train or yard service who
wear glasses for distant vision, enginemen having less
than 20-30 vision in either eye and other employees
who have less than 20-70 vision in either eye must be
re-examined annually.
(c) After any accident in which they are concerned
which may have been caused by defective vision,
colour sense, or hearing,,
(d) After any serious accident or illness or severe
inflammation of the eye or eyelids,
(e) Before promotion. This does not mean that" a
freight conductor should be examined previous to his
appointment as passenger conductor, or engineer in
6 freight service previous to appointment in passenger
service; but that freight brakemen shall be examined
before being promoted to freight conductor, and
firemen being promoted to engineer.
(/) Employees with hearing less than 20-20 in
either ear must be examined semi-annually.^
■ (g) For an individual employee at such periods as
may be designated by the Company's Chief Medical
Officer.
30. (a) Employees in Class A and B who are examined
by a committee shall be given an outside or field test. A
bracket pole with two dolls or two straight poles (spaced
the same distance as dolls on the standard bracket pole)
carrying four standard semaphore arms and lights will be
used.    A clear sky background, tests to be made standing.
(b) In making the tests candidates shall approach
the signals from a point where they are unable to see
them, and not be credited with being able to read
signals unless they can promptly call changes as made
in position of arms and colour of lights.^
(c) The test with and without glasses shall be made
at distances varying from 5,000 to 200 feet.
(d) Committee to record the different distances at
which the employee being examined can promptly see
the signals, and shall forward this information together with their recommendations as to the service
to which he may be assigned to the*
