This action was originally commenced against Williams to recover of him about $1500 alleged to be owing to the plaintiffs for materials supplied by the plaintiffs to him for erecting buildings on certain lots owned by him in the city of Wilmington. The plaintiffs claimed and sought to enforce a lien upon these lots under the act of 1868-’69, chap, 117. Williams made no defence. The Association claimed an estate in the lots under sundry mortgages made to them by Williams, and was allowed to become a defendant.
It is found that plaintiffs at the request of Williams began to supply the materials on 16th October, 1869, and continued to do so until 20th September, 1870 ; that the prices charged are reasonable; that the materials were used upon the buildings put up on the lots in question, v\ hieh in October, 1869, were the property of Williams ; on 7th October, 1870, .the plaintiffs filed a claim for lien in proper form with the Clerk of the Superior Court of New Hanover county.
1» It was objected to the sufficiency of this claim that it was *448for a lien on two lots separated by a street. We do not see that this is material under the circumstances of this case. If the two lots had been sold or mortgaged to different persons, it might be necessary as between them, and to settle their respective liabilities to contribution, to ascertain as well as could be, the value of the materials used on each lot. But the lien of the material man for his whole debt would cover both lots. When materials are furnished under a single contract for buildings put up on two lots, it cannot be expected of the vendor to know how much is used on one of them and how much on the other. In this case as the Association is the assignee of the whole property subject to the plaintiff’s lien, it can scarcely be material to distribute the burthen between the several lots. If it becomes material, that can hereafter be done.
2. It is agreed that as the act of 1868 — ’69, chap. —, which was in force in**October, 1869, when plaintiff made his contract, and began to furnish the materials, required the notice of the lien to be filed with the Register of Deeds; and as the notice in the present case was filed with the Clerk of the Superior Court as directed by the act of 1869-10, chap. 206, sec. 4, (ratified 28th March, 1810), the proper notice was not given.
We are of opinion that in that respect the latter act repealed the former, and the notice being filed in conformity to the law existing when it was filed, was filed in the proper office.
8. The main question is whether the claim of the plaintiff has priority over the mortgages to the defendant.
The first mortgage to the Association was on 20th January, 1870, and two others were made on 27th July, and 16th Augut, respectively.
If it were a matter of importance, it might be a nice question whether the date of the attaching of plaintiff’s lien was governed by the Act of 1868-69, or by that of 1869-70. But we do not think we need determine that question, for by a fair construction of both, the lien begins from the time when the materials were begun to be furnished. The filing of notice relates back to that time. This is expressly enacted by the act *449of 1869-NO, chap, 206, sec. 2; and we think it follows from the provisions of the act of 1868-69.
The first section says: 1. A lien may be and is hereby created under the provisions of this act in the following cases. * * * * 2. Where any person furnishes any material, &c.” Section 3 provides where notice of the lien shall be filed. Section 4, that it shall be filed within thirty days after the furnishing of the materials. Section 12, enacts that the priorities created by the act are to be settled by the priorties of the notices filed.
It must be clear, that unless the claim when filed has relation back to the commencement of the furnishing the materials, the object of the act would be liable to be defeated at the pleasure of the vendee of the materials, by his selling or mortgaging his estate. The act would be idle and inefficacious against the very mischief it was intended to cause. The Assembly might have required notice to be filed of every dray load of materials as it was delivered, but this would have been inconvenient and costly. By allowing the'notice tobe filed after the whole has been delivered, it has put on a purchaser while the delivery is in progress, the duty of informing himself whether materials have been delivered or not, and under what sort of contract. This is in conformity to the construction which has been put on similar statutes in other States. Phillips Mechanics’ Liens, sec. 215. Nibbe v. Brawhn, 24 Ill., 268.
We think the notice of lien had relation back and was prior to the claim of the defendant, as to the materials furnished before the date of the mortgage.
4. The right to priority of lien for those furnished afterwards, though equally clear, stands on a somewhat different foundation. If the mortgagee had immediately gone into possession and notified the material man to discontinue the furnishing of materials, a different case would have been presented from the present. It has been held, that in such a case, if the original contract for materials was entire, the vendor would have a right *450to go on and complete bis contract, notwithstanding the mortgage. It is not necessaiy for us to express any opinion on sueh a case.
Here it does not distinctly appear whether or not the mortgagee knew that materials had been furnished by the plaintiif, and continued to be after the mortgage. We think he must be presumed to have known it. It was his duty to have informed himself of the condition of the property in this respect when he bought it. Tet he gives no notice to discontinue furnishing materials, but acquiesces in the continuance. He receives the benefit of the value of these materials in the increased value of the property, and is therefore bound to allow it as a prior lien. This rule seems to us reasonable, and is' in conformity to the decisions of other States in like cases. Phillips, sec. 228; Watkins v. Wassall, 15 Ark., 73; S. C. 20 Ark., 310; Planters Bank v. Dodson, 9 S. & M., (Miss.,) 527.
It is otherwise where a sale is made, or a mortgage duly registered, before the materials are begun to be furnished, although the mortgagor remains in possession. In such case, the material man has notice of the mortgage, and furnishes the materials on the sole credit of the mortgagor and his estate. Jessup v. Stone, 13 Wis., 466; Hoover v. Wheeler, 23 Miss., (1 Cush.,) 314.
