(f)  The Commission may refer to the Traffic and Highway Board
created under Title I hereof any service proposed under an applica-
tion for a certificate. The Board shall as speedily as possible give
the Commission its recommendations with respect to the proposed
service, but such recommendations shall be advisory only.

(g)  Certificates shall be effective from date specified therein and
shall remain in effect until suspended or terminated as herein pro-
vided. Any such certificate, may, upon application of the holder
thereof, in the discretion of the Commission, be amended or revoked,
in whole or in part, or may, upon complaint, or on the Commission's
own initiative, after notice and hearing, be suspended, changed, or
revoked, in whole or in part, for wilful failure to comply with any
lawful order, rule, or regulation of the Commission, or with any
term, condition, or limitation of such certificate; provided, however,
that no certificate shall be revoked (except application of the holder)
unless the holder thereof wilfully fails to comply, within a reasonable
time, not less than 30 days, to be fixed by the Commission, with a
lawful order of the Commission commanding obedience to the rules
or regulations or orders of the Commission, or to the term_{ con-
dition, or limitation of such certificate found by the Commission to
have been violated by such holder. No certificate shall be issued to
an applicant proposing to operate over the routes of any holder of a
certificate unless and until it shall be proved to the satisfaction of
the Commission, after hearing upon reasonable notice, that the service
rendered by such certificate holder, over such route, is inadequate
to the requirements of the public convenience and necessity; and
provided, further, if the Commission shall be of the opinion that the
service rendered by such certificate holder over such route is in
any respect inadequate to the requirements of the public conve-
nience and necessity, such certificate holder shall be given reasonable
time and opportunity to remedy such inadequacy before any certificate
shall be granted to an applicant proposing to operate over such route.

(h) No certificate under this section may be transferred unless
such transfer is approved by the Commission as being consistent
with the public interest.

(i) No carrier shall abandon any route specified in a certificate
issued to such carrier under this section, unless such carrier is author-
ized to do so by an order issued by the Commission. The Commission
shall issue such order, if upon application by such carrier, and after
notice and opportunity for hearing, it finds that the abandonment
of such route is consistent with the public interest. The Commission,
by regulations or otherwise, may authorize such temporary sus-
pensions of routes as may be consistent with the public interest. The
fact that a carrier is operating a route or furnishing a service at
a loss shall not, of itself, determine the question of whether abandon-
ment of the route or service over the route is consistent with the
public interest as long as the carrier earns a reasonable return.

Schedule of Fares, Regulations, and Practices.

joint fares established for through routes over which it performs
transportation subject to this sub-title in conjunction with another
