Second, where the courts of law do not, or did not, recognize any right, and there- fore could give no remedy, but where the courts of equity recognize equitable rights and, of course, give equitable relief. This has been denominated the exclusive juris- diction. In this class are trusts, charities, forfeited and imperfect mortgages, penalties and forfeitures, imperfect consideration. Uses and trusts have been supposed to have had their origin in the restrictions laid by parliament upon conveyances in mortmain, that is, to the church for chari- table, or rather for ecclesiastical, purposes. It may well be that the doctrine of equita- ble titles and estates, unknown to the com- mon law but which could be enforced in chancery, had its origin in conveyances to individuals for the use of the church in order to avoid the operation of these re- strictions, the conscience of the feofee being bound to permit the church to have the use according to the design and intent of the feoffment. But conveyances in trust for the use of the church were not by any means the only cases in which it was desirable to convey the legal title to one for the use of another. In many instances, such a conveyance offered a convenient mode of making pro- vision for those who, from any circum- stances, were unable to manage property advantageously for themselves, or to whom it was not desirable to give the control of it; and the propriety in all such cases of some protection to the beneficiary is quite apparent. The court of chancery, by rec- ognizing that he had an interest of an equitable character which could be pro- tected and enforced against the holder of the legal title, exercised a jurisdiction to give relief in cases which the courts of com- mon law could not reach, consistently with their principles and modes of procedure. Mortgages, which were originally estates conveyed upon condition, redeemable if the condition were performed at the day, but absolute on non-performance, the right to redeem being thereby forfeited, owe their origin, in the modern conception of
