Ordered, That whenever the accumulation of Mail matter at any Post Office in consequence of prior failures of the Mails on Routes centering at such Offices, becomes so great that it cannot be sent forward by the means of conveyance contracted for by the Department, the Postmasters may be instructed, generally or specially, to have the Contractors to make an extra trip for its conveyance, at a price not exceeding that of a regular trip, and if that be impracticable, to make other provision for its conveyance, provided it can be done on reasonable terms.1
