The opinion
McF addin, J., concurring. 'Stripped of all extraneous matters, the question here posed is:
“Do the trustees of a public charitable trust have the power to use, in their discretion, a part of the surplus, arising from operations of the trust, to discharge moral obligations originally contractual?”
I think the trustees have such power. I concur to emphasize that the holding in the case at bar is limited to an affirmative answer to that question.
