THESE cases come here from the Circuit Court of the United States for the District of Iowa,–the former by appeal, and the latter by writ of error. In 1857, the Des Moines Valley Railroad Company, by its then corporate name, in order to secure the payment of its bonds, executed to certain trustees a mortgage of its road, property, and franchises, 'together with the tolls, rents, and profits to be had, gained, or levied therefrom.'One of the provisions of this mortgage was as follows:–– 'It is hereby further provided, that until failure to pay the interest on said bonds, or to pay the principal at maturity, or to apply, appropriate, set apart, and deposit the several sums of money to be applied, appropriated, set apart, and deposited, as hereinafter provided, the said party of the first part shall have the sole right to the possession, use, management, and control of the said mortgaged property and premises, and of the receipts and revenues thereof, as if this instrument had not been made; but if the said party of the first part shall fail to pay or cause to be paid the principal of the said bonds, or any of them, at the maturity thereof, or shall fail to pay or cause to be paid the interest on the said bonds, or any of them, or any part thereof, on any day whereon the same is made payable by the terms of the said bond, and the same shall remain unpaid for the space of six months after having been demanded, whereby at the option of the holders of one-third in amount of all the outstanding unconverted and unredeemed bonds the principal sum secured thereby shall become immediately payable, or shall fail to apply, appropriate, set apart, and deposit the several moneys required to be applied, appropriated, set apart, and deposited, as hereinafter provided, then and in that case it shall be lawful for the said parties of the second part, their survivor or successor or successors, and it shall be their duty, to enter upon and take possession of all and singular the property, premises, and franchises hereby granted and conveyed, or so expressed or intended to be, and by themselves, or their agent or agents, substitute or substitutes, duly constituted, have, use, operate, and employ the same, making from time to time all needful repairs, alterations, or additions, collect and receive all the tolls, rents, or profits to be had or gained therefrom, and apply all the moneys arising therefrom to the payment of the interest due and to grow due on all the said bonds which may be outstanding, unconverted, and unredeemed, and to the payment of the principal of all and each and every of such bonds when such principal shall become due and payable.' In 1868 the company executed a second mortgage to certain other trustees, in which was conveyed the road with its appurtenances, and 'also all rents, issues, income, tolls, profits, currency, moneys, rights, benefits, and advantages derived or to be derived, had or received therefrom by said company in any way whatever.''To have and to hold the above granted and bargained premises, with the appurtenances thereof, unto the said trustees, and to the survivors and survivor of them, and to their and his successors and successor, and their and his assigns, in trust, and upon the trust, uses, and purposes hereinafter expressed, of and concerning the same, for the use and benefit of the person or persons, firm or firms, bodies politic or corporate, who shall hereafter at any time become the purchasers of holders, owners or bearers, of any or either of said bonds, subject to the terms, provisions, and stipulations in said bonds contained, and also subject to the possession and management of said railroad and property by said eompany, and its successors and assigns, so long as no default shall be made in the payment of either interest or principal of said bonds, or in any or either of them, or in payment of the amount of money, as is herein provided for the sinking fund, and so long as the said company shall well and truly observe, keep, and perform all and singular the covenants, agreements, conditions, and stipulations in said bond and in this indenture contained and set forth, and which are to be observed, kept, and performed by and on the part of said company. 'And it is agreed, in case of the default of the payment of the semi-annual interest as above provided, that said trustees and the survivor or successors of them are hereby expressly authorized and empowered, upon the request in writing of a majority in interest of the owners or holders of said bonds, to enter into and upon, and to take actual possession of, all the property, real and personal, rights, franchises, and privileges, of the premises hereby conveyed, and each and every part thereof, and by themselves, or by their attorneys or agents, have, hold, use, and enjoy the same, and from time to time make all repairs and replacements, and all useful alterations, additions, and improvements thereto, as fully as the parties of the first part might have done before such entry, and to collect and receive all tolls, freight, incomes, rents, issues, and profits of the same, and of every part thereof.' The trustees never took possession; but, default having been made in the payment of interest on both mortgages, the trustees in the second mortgage, in July, 1872, commenced suit to foreclose in one of the State courts, making the railway company the trustees in the first mortgage, and various judgment and lien creditors of the company parties defendant, and, among others, the Illinois and Mississippi Telegraph Cpmpany. No receiver was applied for or appointed pending the foreclosure proceedings, except as hereinafter stated. On May 31, 1873, a decree of foreclosure was entered by the State court, fixing the priorities of the several parties, and holding that the telegraph company's judgment, hereinafter mentioned, was a lien subject to the mortgage in suit and to other specified liens. The decree ordered a sale of the mortgaged property by the sheriff on special execution, but, as originally entered, made no provision as to the possession or earnings of the road (which was still in the possession of the railroad company, and operated by it) between the date of the decree and the sale which the decree ordered. On the thirteenth day of June, 1873, the telegraph company issued execution on a judgment for $23,734.10, which it had on the 24th of May, 1872, obtained against the railroad company in the Circuit Court of the United States for the District of Iowa, and garnished, under the statute of the State, moneys in the hands of the agents of the railroad company at its various stations, received by them from the income and earnings of the road. The trustees in the first and second mortgages filed, June 20, 1873, the present bill in equity against the telegraph company to enjoin the said proceedings upon the execution under its judgment. The bill was, the twenty-seventh day of June, 1873, amended so as to make the Des Moines Valley Railroad Company a defendant; and a temporary injunction, as prayed for, was allowed. On Sept. 9, 1873, after a sale had been advertised by the sheriff, application was informally made to the State court, by the trustees under the first mortgage, for a modification of the decree of May 31, 1973; and the same was modified by appointing a 'special receiver of all the income and earnings of the road' between the date of the decree or sheriff's first publication of notice of sale and the sale to be made by him. This was done, saving the rights of the telegraph company. The special receiver took possession Sept. 15, 1873. The sale by the sheriff under which the purchasers were let into possession took place Oct. 17, 1873, and left a large amount of the mortgage bonds unpaid. Between the date of the decree of May 31, 1873, and Sept. 15, 1873, when the special receiver took possession, the road was operated by the railroad company; and, during this period, the net earnings were $27,147.96. Coykendall, who was garnished, had received $27,000; and judgment in the suit at law was rendered against him for that amount. The Circuit Court dismissed the bill of the complainants.
