REVISION OF MANUAL.

Your Committee desires to remove an ambiguity in the "Table of Theoretical and Practical Leads" on page 92 of the Manual by inserting the word "theoretical" in the captions of columns II and III.

CONCLUSIONS.

Your Committee recommends for adoption and publication in the Manual:

I. As representing good practice:

2.

(a) Tie Plates-General principles to be followed in the design.
(b) Specifications for Steel Tie Plates.

(c) Specifications for Wrought Iron Tie Plates.

(d) Specifications for Malleable Tie Plates.

(e) Track Bolts-Facts and general principles to be taken into consideration in the design.

(f) Specifications for Track Bolts.

(g) Specifications for Spiral Spring Nutlocks.

(h) Specifications for Ordinary Track Spikes.

(i)

Specifications for Screw Spikes.

(j) Anti-creepers-General requirements to be met in the de

sign and manufacture.

As representing good practice:

Typical plans of Nos. 8, 11 and 16 main line turnouts.

3. As desirable agencies to obtain a better class of section foremen:
(a) The application of the principle of apprenticeship for a de-
fined period during which the rate of pay shall be the
same as a laborer, following which those men who show
the necessary qualities for foremanship to be given an
increase in compensation and the title of assistant fore-
man. From this position those men should be promoted
to that of section foreman.

(b) The application of a method of education by periodical
instruction in the form of meetings, at which supervising
officers should instruct as to practice and encourage
discussion between the men.

(c) The application where possible of an educational system, such as is being conducted on several of the larger railways, for which articles are written by supervising officers dealing with the best practices, which articles are printed and sent to foremen and assistant foremen free of cost, following which an examination is conducted the results of such and promotions depending on

examinations.

4. The "Table of Functions of the Ten-chord Spiral" submitted herewith, as supplementing and completing the table on pages 102-110 of the Manual and superseding the Table on page III.

5. The headings "W Length Theoretical Point to Toe" and K = Length Theoretical Point to Heel" in place of “W = Length Point to Toe" and "K= Length_Point to Heel" in columns II and III, Table of Theoretical and Practical Switch Leads on page 92 of the Manual.

Your Committee recommends that subjects 2 and 3 be reassigned, the former with instructions as to the features to be studied.

Respectfully submitted,
