vided in Section 147 hereof. In such latter case it shall be
the duty of the purchaser to remove said markers promptly
at the expiration of such five days and return them either to
the original owner of the motor vehicle or to the Commis-
sioner of Motor Vehicles, and it shall be unlawful for the
purchaser or any person other than the person to whom such
markers were originally issued to have the same in his posses-
sion after the expiration of such five days, whether in use
or not; provided, however, that in the case of a transfer of
ownership, the original owner may register another motor
vehicle under the same number upon payment of a fee of
one dollar ($1.00) where such motor vehicle is of less or

equal horse-power or tonnage as that originally registered;

or upon payment of a fee of one dollar ($1.00) and the differ-
ence between the fee originally paid and that due, in case
the new motor vehicle be properly registered in a higher class:
:and provided further that upon such transfer of ownership
and the return of such registration certificate and number
plates or markers, with the application prescribed for use in
such cases, the original owner shall be entitled to a refund of
the amount paid for registration markers and certificate on
a basis of quarterly periods of use yet remaining.

LICENSE TO OPERATORS.

143. No person shall operate a motor vehicle upon any
highway of this State until he first shall have obtained a
license for the purpose. The Commissioner shall require an
actual demonstration of the qualifications of the person apply-
ing for such license, and, in addition, may refuse to issue
the same if, in his judgment, the safety of the public would
be jeopardized thereby, but said applicant shall have the
right to appeal if license is refused, as provided elsewhere in
this sub-title. Any person desiring to receive a chauffeur's
or motor vehicle operator's license shall first obtain an exam-
ination permit or an instruction license upon paying the sum
of one dollar ($1.00) to the Commissioner of Motor Vehicles,
which such instruction license shall entitle the person to
whom it is issued to operate a motor vehicle only when accom-
panied by a regularly licensed operator, for a period of
thirty days Prom the date of its issue. at which time it shall
