Railway Demurrage.—A letter has been received by the
Association of Chambers of Commerce from the Railway
Clearing House on the subject of demurrage. It is stated
that the adjustment of railway rates and demurrage
charges is receiving the careful consideration of the railway
companies, but some unavoidable delay has occurred through
the illness of the chairman of the conference. It is hoped,
however, a definite answer to the claims of the traders will
be given shortly. In reply to a request from the railway
managers for information as to the association’s proposals
for the formation of advisory committees to deal with
matters which are causing friction between the traders and
the companies, a letter has been addressed by the secretary
of the Association of Chambers of Commerce giving details
of the Chambers’ proposal. It is suggested that the local
Chambers should appoint a small committee in each district
to meet once a month to consider such questions as cartage
areas, delays in delivery, withdrawal of facilities, loss
through damage or pilfering, group rates, alterations in'
working classification, local demurrage, station and siding
accommodation, &c. On this committee one or more repre-
sentatives of the railway companies, it is held, should be
appointed. The smaller of these matters could be dealt
with by these local committees, while the larger matters
could be referred to a central committee, which would
consist of representatives of the Associationof Chambers of
Commerce.
