57. An officer who is promoted in the ordinary 
course in the Colony in which he is serving will, in 
the absence of any statutory provision to the con- 
trary, receive the salary of his new scale, grade, or 
appointment, if it be available, as from the date when 
the vacancy occurred in the superior post, whether 
he be in the Colony or on leave of absence at the date 
in question. 
58. When the salary of an officer is on an incre- 
mental scale, the holder is not entitled to draw any 
increment as of right, but only by sanction of the 
Governor. In the case of a subordinate officer a 
certificate is required from the head of his department 
that he has discharged his duties with diligence and 
fidelity. 
59.—(1) The period of service qualifying for an 
increment shall be reckoned from the day on which 
the officer first begins to draw any of the salary of his 
office. 
(2) Where an officer already in the service of the 
Colony 1s appointed in the ordinary course of promo- 
tion to an office in the Colony carrying salary on an 
incremental scale and the new office is not superior in 
pensionable status to the old office the following rules 
shall apply :— 
(a) If at the date of appointment the salary 
of the officer is not less than the minimum of the 
new office, he shall retain the salary which he is 
drawing until he has by length of service at his 
new incremental rate (or if he was qualifying for 
increment in his former post then at his former 
and his new incremental rates respectively) 
earned such an amount of increment as will bring 
his salary up to the next higher incremental step 
ir the new scale. From that date he shall be 
eligible to draw salary accordingly and the date 
shall henceforth become his ordinary incremental
