In spite of its moderation the Northern Pacific was not over-prosperous. Its passenger earnings remained small, being scarcely greater in 1888 than they had been in 1884; and while its freight earnings increased from $7,867,367 in 1884 to $10,426,245 in 1888, and to $15,600,320 in 1889, this was so far offset by increased operating expenses that the increase in net earnings from both passengers and freight was only $2,223,194. Construction meanwhile caused an increase in funded indebtedness outstanding of $15,202,000, to say nothing of $20,981,000 of branch-line bonds which the road by 1889 had guaranteed; and the floating debt began to grow uncomfortably large.[573] At the same time, if Mr. Villard is to be believed, officials in charge of the operation of the road were eager for appropriations for the improvement of the track, the replacement of wooden by metal bridges, additional motive power and rolling stock, enlargement of terminal facilities, and the purchase and construction of new lines. The truth was that the problem of getting the road built had been more important than that of how it was to be built; so that much work had been done in a hasty and imperfect manner which it was now advisable to renew. Since, then, there was need for additional capital, while it was unsafe to increase the fixed charges of the road, the managers felt called upon to devise a scheme whereby these circumstances should both, at least in appearance, be met. Their solution was the proposal of a large refunding mortgage to retire as soon as possible existing mortgages, and to provide a balance which could be spent upon the line. If, they argued, bondholders could be induced to accept new 4 per cent or even 5 per cent bonds in exchange for their 6 per cent securities, the road would be free to issue new additional bonds until the margin of charges so obtained should have been taken up. The plan was worthy of its ingenious promoter, Mr. Villard, and will be criticised in the proper place.
