The training and entering of the merlin, eyess or wild-caught, differs in no important particular from that of the peregrine which is to be flown at rooks. Only the reclamation is much more speedily effected. Often it can be completed, even in the case of an adult jack, in less than a fortnight--with the exercise of diligence, of course. An eyess, well hacked, can be manned in less than a week. This, however, does not mean that they can be trained to larks in that time. Writers on falconry sometimes inadvertently lead their readers astray by declaring that the merlin is easily trained. What the writer means is probably that they are easily manned and made to the lure. This is so; but the preparation for flying in the field, at least at larks, is quite a different matter. Merlins, like all other hawks, differ greatly in temperament. Occasionally you will find a whole nest of them quite free from vice. Such hawks are all easily trained for the field. But more often these little creatures are imbued from the first with a disposition to carry. And to fly a merlin at larks before she is cured of this weakness is to involve yourself in endless trouble. Eyesses are as bad as haggards--often worse. Consequently, when the hawk is manned and made to the lure, more than half your work is still before you. A non-carrying merlin can be trained in less than a week after being taken up from hack, whereas a determined carrier will hardly be safe to fly in double that time. [Illustration: TRAINED MERLIN]
