Section 6 of Said Rule Is Hereby Amended by Adding After the Word

"substitutes" in line 6 the words "resident in the counties which are supplied wholly or in part by the road on which the vacancy exists;" so that as amended the section will read:

6. There may be certified and appointed in each State and Territory, in the manner provided for in this rule, such number of substitute clerks, not exceeding the ratio of one substitute to ten regular clerks, in such State or Territory as the Postmaster-General may authorize, and any vacancies occurring in class I in any State or Territory in which substitutes have been appointed shall be filled by the appointment thereto of those substitutes resident in the counties which are supplied wholly or in part by the road on which the vacancy exists, in the order of their appointment as substitutes, without further certification. The time during which any substitute is actually employed in the service shall be counted as part of his probation.
