That the machinery in question was adapted to the use for which the building was constructed is conceded, and, without further pursuing the authorities, I will briefly refer to those cited in the opinion of my learned brother, Allen, J., in support of the proposition that these were not fixtures. Hellawell v. Eastwood, 6 Exch. W., H. & G., 295, was a case between landlord and tenant. The alleged fixtures, presumably, were put in by the tenant, as they were distrained for rent. The object and purpose of the annexation was stated by the court not to have been to improve the inheritance, but merely to render the machines steadier and more capable of use as chattels.

Walker v. Sherman, 20 Wend. 636, was partition, and although the machines in dispute had been for many years in the building, the difficulty was that they were not affixed or fastened to the building in any manner, and the commissioners treated them as personalty; but other machinery in the same factory, which was fastened to the building, was treated as realty. (See pp. 637, 638.) This case holds, in respect to machinery, that the two characteristics of adaptation to the enjoyment of the realty and annexation to it must concur, but that where the former characteristic is present, the slightest fastening will be sufficient to constitute annexation. (See pp. 651, 653, 655.) It is enough that it is permanently or habitually attached. In Vanderpocl v. Van Allen, 10 Barb. 157, the machines merely stood upon the floor, without being attached in any way, except by the belts which were used for motion and not for fastening, except as to some of the pieces, in respect to which cleats were used to make them stand level, and there was no evidence of any intention to make them part of the freehold, but all the facts tended to the contrary. Murdoch v. Gifford, 18 N. Y. 28, has already been referred to, and only establishes that the mode of attachment shown in that case was not of itself sufficient to make the machines fixtures, where the purpose of the attachment was solely for the more convenient use of them as chattels, and in the absence of any intention that it should be permanent.

The finding of the court that, in the present case, the original intention of the annexation was to make the machinery permanently a part of the building is not, I think, unsupported by evidence. The building was proved to have been erected especially for the purpose of a twine factory, and with reference to holding this description of machinery. The machines were of great weight, many of them weighing from one to four tons. They were all permanently fastened to the floor of the building, and it is conceded that they were adapted to the purposes for which the building was erected. The plaintiff testified that they were placed there for permanent use. The fair interpretation of this evidence is that they were placed there for permanent use in that building; they constituted part of the twine factory, and about two-fifths in value of the entire establishment; and it appeared in evidence that although they were capable of removal they would be of less value if taken out and sold than if they remained where they were, as part of the factory. From this evidence the court was, I think, justified in finding that they were intended as a permanent part of the structure, quite as much so as the portable grist-mill in the case of Potter v. Cromwell, 40 N. Y. 287. The dealings between the plaintiff and his vendee, also showed that they were regarded as fixtures which passed with the land; and although, if the property had in its own nature a determinate legal character, either as realty or personalty, the manner in which the parties treated it would not change that character; yet when, as in this case, the character of the property is not so fixed, but depends upon the intention with which it was annexed, the conduct of the party who annexed it has an important bearing, as throwing light upon that intention. He evidently understood that it was part of the realty, which he could not have done if he had placed it on the premises for temporary use merely, and with the intention that it should remain personalty. When contracting for the sale of the property, he described it as the real estate situate in Johnsville, viz., the twine factory and flax-mill, etc., etc., with the machinery, etc., and sold the whole for a gross sum of $28,000. By this contract he includes the machinery under the general head of real estate, and in fulfillment of that contract he tendered a conveyance describing the land only, and took back a mortgage for $21,000 of the purchase-money, describing the land only, although the land and buildings, without the machinery, were worth a much less sum than the amount of the mortgage. The fact that at the request of the purchaser he afterwards executed a supplementary bill of sale is not of much significance. It is found by the court that there were some tools and machinery which were loose and are not claimed in the action. The bill of sale also includes fixtures, which necessarily passed with the deed. It was not a necessary instrument, as whatever was personalty would have passed by delivery; but it was probably given because it conformed to the intention of the plaintiff and was a simple confirmation of what he believed he had already done, and was requested by the purchaser or his adviser.

After it has been so repeatedly declared by the courts that the character of articles of the description now in controversy attached to a building, whether they are to be regarded as realty or personalty, is to be determined by the intent of the party attaching them, it would be peculiarly unjust to depart from that doctrine in a case like the present, where the owner of the land and buildings, who himself made the annexation, and necessarily knows the intent with which it was made, afterwards sells the whole establishment and takes for the purchase-money a mortgage manifestly intended to cover all the property sold, but which would be a totally inadequate security if the property which he had annexed were not treated as a part of the realty. There can be no equity in such a case in favor of a mere judgment-creditor of the vendee as against the mortgagee.
