[Sidenote: Shrink]

"5. The number of passes and speed of train shall be so regulated
that, on leaving the rolls at the final pass, the temperature of the
rails will not exceed that which requires a shrinkage allowance at
the hot saws, for a 33-ft. rail of 100 lb. section, of 6-1/2 in. for
thick base sections and 6-3/4 in. for A. S. CC. E. sections, and 1/8
in. less for each ten pounds decrease of section, these allowances
to be decreased at the rate of 1-100 in. for each second of time
elapsed between the rail leaving the finishing rolls and being
sawed.

"The bars shall not be held for the purpose of reducing their
temperature, nor shall any artificial means of cooling them be used
between the leading and finishing passes, nor after they leave the
finishing pass.

[Sidenote: Section]

"6. The section of rail shall conform as accurately as possible to
the templet furnished by the Railroad Company. A variation in height
of 1-64 in. less or 1-32 in. greater than the specified height, and
1-16 in. in width of flange, will be permitted; but no variations
shall be allowed in the dimensions affecting the fit of splice bars.

[Sidenote: Weight]

"7. The weight of the rail shall be maintained as nearly as
possible, after complying with the preceding paragraph, to that
specified in the contract.

"A variation of one-half of one per cent. from the calculated weight
of section, as applied to an entire order, will be allowed.

"Rails will be accepted and paid for according to actual weight.

[Sidenote: Length]

"8. The standard length of rail shall be 33 ft.

"Ten per cent. of the entire order will be accepted in shorter
lengths varying by 1 ft. from 32 ft. to 25 ft.

"A variation of 1/4 in. from the specified lengths will be allowed.

"All No. 1 rails less than 33 ft. shall be painted green on both
ends.

[Sidenote: Finishing]

"9. Care shall be taken in hot-straightening rails, and it shall
result in their being left in such condition that they will not vary
throughout their entire length more than four (4) in. from a
straight line in any direction for thick base sections, and 5 in.
for A. S. C. E. sections when delivered to the cold-straightening
presses. Those which vary beyond that amount, or have short kinks,
shall be classed as second qu
