Taxes are prior in lien to all other liens except judicial costs; 8 Woods 484; 110 Ν. Υ. 250; 41 Ν. J. L. 285. In many states liens are given by statutes to certain favored creditors, who thus acquire priority over mortgage bonds prior to the inception of their claims. The or- dinary mechanic's lien statute does not apply to railroads unless expressly declared to do so. The contractor who constructs a railroad has no lien thereon as a matter of right. The fact that he has possession does not give him a lien; 1 Wall. 254; 11 id. 459. The courts construe such statutes strictly. Thus, a statute giving a lien for materials, supplies, and labor does not give a lien for money loaned to pay for them; 39 Fed. Rep. 436. And a lien for materials will be allowed only for such materials as pass into the permanent structure, and not for trucks, scales, etc.; 27 Fed. Rep. 178. A contractor's lien for work done will be limited to the embankments and structures actually made by him, as distinguished from the land and right of way; 83 Fed. Rep. 386. It has been held that a statute giving a lien to persons furnishing supplies necessary to the operation of a manufac- turing company prior to the lien of an earlier mortgage is not unconstitutional as special or class legislation; 90 Va. 126. Such "supplies" are only such things as contribute directly to carrying on the work in which the company is engaged and not, e. g., goods supplied to a "come pany store" maintained by a furnace com- pany; 81 Fed. Rep. 451. But, while the courts construe such statutes strictly in determining the kind of claims to be ad- mitted under their provisions, they con- strue them liberally as remedial statutes in determining the formalities to be ob- served under their provisions; 35 Fed. Rep. 442. A very common statutory lien of this class is the lien for labor, usually limited as to the duration of the labor for which a lien can be filed, and also as to the class of employes entitled to take advantage of the provisions of such a statute; 35 Fed Rep. 436; 81 id. 453. The "six months' rule," or as it is usually called, from the case in which it was adopted by the Supreme Court of the United States (99 U. S. 235), the rule in Fosdick v. Schall, allows parties who have furnished labor or supplies within six months ante- cedent to the receivership priority, at least so far as income received during the receivership is concerned, over mortgage bondholders. It has been held that the rule applies only to railroads; 128 U. S. 416; not to manufacturing corporations; 35 Fed, Rep. 436; 42 id. 372; nor to steamship lines; 50 id. 812; nor to a hotel company; 106 Ν. Υ. 423. But see, contra, an Alabama case discussing the authorities and extend- the rule to private corporations generally; 29 L. R. A. 623. See RECEIVERS. Mortgage or Lien. Where preferred stock is issued under a stipulation in the certificate that "no mortgage or lien of any nature" shall be placed upon the property of the company without the unanimous con- sent of the preferred stockholder, the words "mortgage or lien of any nature" do not include claims of general creditors. 148 Ky. 379, 146 S. W. 752. As to the right of a mortgagee to posses- sion, see 5 Harv. L. Rev. 245. See ROLLING STOCK; RECITALS; TRUSTEE; TRUST DEED; MERGER; LEASE; MAJORITY.

Mortgages in the civil law are of two kinds, conventional and legal. A conven- tional mortgage results from the direct act or covenant of the parties. A legal mort- gage arises by mere act of law. A mortgage may be acquired in three ways. First, with the consent of the debtor, by his agreement. Second, without the owner's consent, by the quality and bare effect of the engage ment, the nature of which is such that the law has annexed to it the security of a mortgage. Third, where a mortgage is acquired by the authority of justice: as where a cred- itor who had no mortgage obtains a decree of condemnation in his favor. When the creditor is put into possession of the thing, movable or immovable, he has a right to keep it until he is paid what is owing him; and the debtor cannot turn the creditor out of possession, nor make use of his own thing without the consent of the creditor. Effect of a mortgage. First, the cred- itor has a right to sell the thing pledged, whether the creditor has it in his posses- sion or not. Under the French law, it was a right to have it sold. Cushing's Domat, p. 647. Second, a right on the part of the cred- itor to follow the property, into whoseso- ever hands it has come, whether movable or immovable. Third, a preference of the first creditor to whom the property is mortgaged, and a right on his part to follow the property into the hands of the other creditors. Fourth, the mortgage is a security for all the consequences of the original deb
