Pierce Butler, Great Northern Railway Company v…
“ The shipments moved on combination rates, being the sum of proportionals made respectively by the Canadian Pacific and the Great Northern, [1] applicable from mines to destinations, and on through bills of lading issued by the former, routing over its railroad to junction with the latter at the international boundary and thence over the railroad last mentioned to places of delivery. The combination rates necessarily reflect agreement, express or implied, between the connecting carriers to establish a through route for continuous carriage from origin on one to destination on the other. ”
