strained by a court of equity upon the impression that the land will thereby be rendered an insufficient security for the debt. Brady v. Waldron, 2 John. Ch. 148.
When Sutton & Co. took their mortgage upon the Canada, but left her in the possession and use of the mortgagors, they impliedly authorized the latter to make such changes, additions, and repairs in her fitment, tackle, apparel, and furniture as might be necessary and convenient for her preservation and use as a ship, so that they did not wilfully depreciate her value as a security for their debt. In pursuance of this authority, the Howes might, as mortgagors in possession, remove from time to time every part of this vessel, including her tackle, apparel, and furniture, and replace it with new, and dispose of the old and displaced material as their property, unaffected by the mortgage. But in case the old material was not so disposed of, and was left on board and passed into the possession of Sutton & Co. when they took possession of the ship, to whom it then would belong would depend on circumstances.
In the consideration of the question, I think it may be assumed that in the case of a bona fide repair, particularly where old material is displaced with new of equal or greater value, that the mortgagor has a right to dispose of the old material as his own. But where no such disposition is made of it, and it is suffered to remain on board as part of the ship's material, and is capable of being used in some form in the navigation of the vessel, I think the old material would still belong to the ship, remain a part of it, and be the property of the mortgagee in possession.
For instance, if the mortgagor in possession should put a new suit of sails on the vessel, and instead of disposing of the old ones should stow them away as suitable material for mending or supplying a rent or lost sail, such old material would remain within the operation of the mortgage and pass to the mortgagee in possession. Under those circumstances the reasonable inference would be that while the mortgagor had, for the safety and convenience of the vessel, added to the value
