Culebra, C. Z., January 1. 1911.
Circular No. 297-b (Superseding Circulars Nos. 297
and 297-a) :

1. By direction of the President of the United States,
hourly employes on the gold roll of the Isthmian Canal
Commission and of the Panama Railroad Company,
who are not accustomed to a tropical climate, will be
allowed four weeks' leave with pay for each year's con-
tinuous satisfactory service after January 1. 1911.

2. This leave will be computed as 28 consecutive days
of eight hours each, to be at the rate of pay per hour
received at the time leave is taken.

3. Employes, who have rendered satisfactory service
for six months or longer subsequent to January 1.191 1,
who resign or who are discharged, except when services
are terminated for cause, will be granted leave on ac-
count of such service at the rate of/two and one-third
days for each full month, total not to exceed*56 days;
but no leave will be granted to an employe who resigns,
or is discharged after less than six months' service.

4. In computing leave earned by service in both 1910
and 1911, or on both the hourly and monthly rolls, the
following rules will govern:

(a) Leave will be. due any time after 10 months' con-
tinuous service, computing the leave as if the employe
had served a full yearof'12 r months.

(6) For each*full' month on the'hourly gold roll in
1910, count one and one-sixth days' leave.

For each full month on the hourly gold roll in 1911,
and subsequently, count two and one-third days' leave.

For each full month on the monthly gold roll, count
three and one-half days' leave.

(c) In these cases if the employe elects to accumulate
any portion of hisleave it must be two weeks, or a multi-
ple of two weeks. •

(d) It should be noted that only American citizens
are entitled to leave for service on the hourly gold roll
in 1910, but for service after 1910 citizenship is not
considered.

5. No leave will be computed on a fraction of a month.
When computation of leave results in a fraction of a
day, a half day, or over, will count as one day. No
credit will be given for less than a half day.

6. Two, four, or six weeks of any leave due may be
left to accumulate, to be taken on termination of service,
or to be added to the next leave due the employe, pro-
vided that not more than 56 days may be taken on ter-
mination of service, and not more than 42 days for the

this rule will be forfeited.

7. Leave without pay may be taken in conjunction
with leave with pay, provided the total does not exceed
42 days.

8. Leave is not a vested right; it nvjst be taken at
the convenience of the department or division when the

charged, leave must be taken in a country affording the
necessary change of climate, and compensation for the
leave period will not be paid until the first pay period
after the employe returns to the Isthmus and reports for
duty. Employes not reporting for duty within 15 days
after the expiration of their leave will forfeit the right
to pay for the leave period and may be discharged.

9. Time lost by an hourly employe on account of
leave without pay in excess of 30 days in one service
year, suspensions for discipline, furloughs, absence from
duty on account of illness, or injury in excess of a total
of 60 days in one service year, will not be credited as
service entitling an employe to leave with pay.

10. The new service year of an employe will date
from the completion of 12 months' continuous service,
exclusive of above deductions.

11. When leave isdue an employe, and he has given
notification of his intention to accumulate same, he shall

the reason for termination of service.

classes, viz.: Distributed and undistributed.

distributed labor.

The time of each artisan and helper while actually

The time of a foreman will be distributed only when he
supervises continuously the labor on one particular job,

unit, such as the foreman of the foundry at Gorgona, a
foreman engaged exclusively in making repairs to steam
shovels outside of the shops, etc.

The time of yard gangs, crews of locomotives and
locomotive cranes, crews of boats transporting material
and men, crane operators, etc., will be distributed only
when an accurate record is kept of the amouut of time
spent on each job, or on each class of work the cost of
which is kept as a unit.

undistributed labor.

All other labor will be charged to the proper subhead
under shop expense.

distributed material.

All material of which at least a portion thereof forms
part of the completed job will be charged directly there-
to.

The cost of tools, templets, dies, fixtures, jigs, etc.,
will be charged directly to a job only when of such
special character that they cannot be used on any other
work.

Patterns will be charged to the cost of castings.

UNDISTRIBUTED MATERIAL.

The cost of all other material will be charged to
proper subhead under shop expense.

other expenses.

percentum which the shop expense is of the distributed
labor, will be shown below the summary.

4. The Examiner of Accounts will keep a debit and
credit account of the shop expense of each shop, and
will submit quarterly to this office a report showing the
balance and character thereof.

The shop expense percentage which each shop will
apply to all work done therein, whether manufacturing
