In the course of training, a thousand difficulties not possible to be forseene by the generall direction, will offer themselues, and appose the maister, and at the sudden must be salued. What will the trainer do? runne to his booke? nay to his braines. He must remember his rule, that indiuisibles and circunstances be beyond the reach of _arte_: and are committed to the _Artificer_ whose _discretion_ must helpe, where _arte_ is to weake: though she giue him great light, by fitting this to that, when he hath found wherfore. _Arte_ setteth downe the exercise and all the knowen circunstances. The person bringes with it some difficultie in execution, where is the succour? _Arte_ will not relent, she can not make curtsie, her knees be groune stiffe, and her iointes fast knit, and yet curtsie there must be. The _Artificer_ must make it, and assist his ladie, which if she had not had a man to be her meane, she herselfe would haue done all, and trusting to man whom she hath made her meane, why should she be deceyued, and her clyentes be abused, where she commendes them of trust? Children that come to schoole dwel not in one house, not in the same streate, nay not in the same towne, they cannot lightly come at one houre, they be not of one age, nor fit for one exercise, and yet they must haue some. The _arte_ knoweth my child no more then my neighbours, but the trainer must, and stay those vncertainties vpon the arrest of _discretion_: being enstructed afore hand in the generall skill though bound but of voluntarie: as the like cause shall lead the like case.
The rule is, no noysome sauour neare the newly exercised: how shall the poore boye do, that is to go home thorough stinking streates, and filthy lanes.
The rule is, change apparell after sweat: what if he haue none other? or not there where he sweateth? Here must the trainers _discretion_ shew it selfe, either to chuse exercises that be not subiect to any such extremities, or to vse them with the fewest. But I am to long, neither neede I to doubt of mens discretion, though I say thus much of it, which many haue and moe wishe for, I shall haue occasion to supplie the rest in the generall teacher.
Thus haue I runne thorough the whole argument of exercises, and shewed not onely what I thinke of them in generall, but also what be the cheife particulars, and the circunstances belonging thereunto: and according to my promise I haue delt with the training maister, and ouertreated him to thinke honorably of his profession, to gather knowledge, where it is abundantly to be got: and last of all to ioine _discretion_ as a third companion to his owne admiration and sufficiency.
