630 LAWS OF MARYLAND. [CH. 344

(b) The proportion so computed for a member age 59 shall
be applied to a member who attains a greater age before he
becomes a member of the retirement system.. The Board of
Trustees shall certify to the Superintendent of Schools of each
county, and the Superintendent of Schools of each county shall
cause to be deducted from the salary of each member on each
and every payroll of such county, for each and every pay-
roll period the proportion of earnable compensation of
each member so computed. But the Superintendent of
Schools of any county shall not have any deduction made for
annuity purposes from the compensation of a member who
elects not to contribute if he has attained age 60 and has com-
pleted thirty-five years of service. In determining the amount
earnable by a member in a payroll period, the Board of Trustees
may consider the rate of annual compensation payable to such
member on the first day of the payroll period as continuing
throughout such payroll period, and it may omit deduction
from compensation for any period less than a full payroll period
if a teacher was not a member on the first day of the payroll
period, and to facilitate the making of deductions it may
modify the deduction required of any member by such an
amount as shall not exceed one-tenth of one per centum of the
annual compensation upon the basis of which such deduction
is to be made.

(c) The deductions provided for herein shall be made not-
withstanding that the minimum compensation provided for by
law for any member shall be reduced thereby. Every member
shall be deemed to consent and agree to the deductions made
and provided for herein and shall receipt for his full salary
or compensation, and payment of salary or compensation less
said deduction shall be a full and complete discharge and acquit-
tance of all claims and demands whatsoever for the services
rendered by such person during the period covered by such
payment, except as to the benefits provided under this subtitle.
The Superintendent of Schools of each county shall certify to
the Board of Trustees on each and every payroll or in such
other manner as the Board of Trustees may prescribe, the
amounts to be deducted; and each of said amounts shall be
deducted, and when deducted shall be paid into said Annuity
Savings Fund, and shall be credited, together with regular
interest thereon to the individual account of the member from
whose compensation said deduction was made.

(d) In addition to the contributions deducted from compen-
sation as hereinbefore provided, subject to the approval of the
Board of Trustees, any member may redeposit in the Annuity
Savings Fund by a single payment or by an increased rate of
contribution an amount equal to the total amount which he
