The guardian of a spendthrift has, at most, an authority over the estate of his ward not coupled with an interest ; and in making sale of his real estate under a license from a judge of probate, he executes a r ere power. The license prescribes the mode of execution ; and as this class of powers is created by law, in derogation of the right of the citizen to manage his own property, and to secure it from being wasted, on the ground that he is himself an unsuitable person to manage it, the reason for enforcing the rule that powers must be strictly executed is peculiarly strong in such cases. Guardians should be held liable for all losses that arise in consequence of their disregard of the terms of their license to sell, both in respect to the manner of making sale and the disposition of the proceeds.

In this case the license to sell was granted upon the petition of the guardian, representing that there was a debt of $976 due from the ward, which was secured by mortgage upon a part of the real estate, and other debts amounting to $250; that it was for the interest of the ward that the whole should be sold; and that, after paying the debts, the balance should be invested for his benefit. The license was granted on the 25th of April 1854. As to the proceeds of the sale, it directs that they be “ put at interest, and secured by mortgage on other real estate, or otherwise well and safely invested for the benefit of said ward.” As the license does not direct the payment of debts out of the proceeds, it would seem to authorize the sale of the land subject to the mortgage. But in such case, as the mortgage would remain upon the land, it would not be safe to invest the proceeds upon the equity as security; and probably this is the reason why the license requires the security to be by mortgage of “ other real estate,” if a mortgage is taken as security. The guardian has disregarded this direction; and instead of paying the *429mortgage debt, as he proposed in his petition to do, be sold the land subject to the mortgage, and took security for a part of the purchase money on the equity of redemption. The result was that he was obliged to take the land, and that the mortgagee, Alpheus Harding, Jr., has foreclosed his mortgage. And thus, after the guardian has expended considerable sums of money in repairs, &c., he has lost the whole land. It is immaterial that the mortgagee is willing that he shall still redeem. He has lost the legal right to do so. The ward himself could hardly have managed the property moré disastrously; and as the disasters have happened in consequence of the guardian’s error in the investment of the proceeds of the sale, in a manner not authorized by the license, he must bear the loss. None of his charges for loss on the real estate, or for money expended upon it subsequently to the sale, can be allowed. The money must be treated as if it had remained in his own hands, and must be accounted for accordingly. The assent of the ward to his proceedings can have no legal validity, since the ward had no legal competency to act in the matter. The very purpose of the guardianship is to take away such competency.

The hay which was sold with the farm, and as a part of it, and returned by the guardian as such, must be accounted for according to the return of the guardian.

Another portion of the proceeds of the sale has been invested as follows: The land was sold to John K. Tenney on the 26th of May 1854, for the sum of $2700, which included $200 as the price of the hay above mentioned. On the 21st of the following November, Tenney sold it to Samuel S. Sinclair. The guardian had not delivered the deed till that time. He took the notes of Sinclair for $1257, secured by a mortgage of the land sold, and also three notes of Sinclair. One was for $200, payable on the 1st of the following October; and two for $100 each, payable in April 1856 and April 1857. These notes were also signed by John Conant as surety. Con ant was a stranger to the guardian, who made inquiries about him, and was informed that he paid his debts punctually, and was considered good for four or five hundred dollars. He had reasonable cause *430to believe that this was true. But considering that Sinclair had been obliged to run in debt for the whole purchase money, and that these notes had a considerable time to run, and the chances of death, sickness and accident to which this single surety was subject, it cannot be regarded as an act of reasonable prudence in a guardian to invest $400 on such security. Even in the execution of private trusts, a power of sale, or of varying trust securities, though to a certain extent discretionary, must not be exercised in an arbitrary or mischievous manner, but only for the benefit of the trust estate ; and the court will enter into the circumstances, and decide upon the propriety or impropriety, of exercising such powers. Hill on Trustees, 471 Sf seq. Much more should the court examine into the circumstances, and require the exercise of care and prudence on the part of a guardian, in whose hands the law has placed the property of a ward which is taken from him by compulsion, to prevent waste and mism an agement.

The note received of William T. Morse, on which $241.26 proved to be due, was signed by two sureties, and payable to and indorsed by Tenney; but it does not appear that either of the parties besides Morse ever had any property or was reputed to have any. When execution was obtained, it was found they had none. So far as is shown, then, the investment was really upon the security of Morse alone. We cannot regard this as an exercise of reasonable prudence. On the whole, we think the decree of the judge of probate should be affirmed.
