This last element in the definition ought not, I think, to be overlooked, for I can conceive cases in which the absolute restraint might, as between the parties, be reasonable, but yet might tend directly to in- jure the public ; and a rule founded on public policy does not admit of any exception that would really produce public mischief; such might be possibly the case if it was calculated to create a pernicious monopoly in articles for English use, — a point I desire to leave open, and one which, having regard to the growth of syndicates and trusts, may some day or other become extremely important." ^ In facility and precision of statement of legal propositions lead- ing up to or summarizing an argument, omitting no essential quali- fication, and expressing neither too little nor too much, Lord Bovven was a master. His clear and comprehensive statement, in Thomas V, Quartermaine,^ of the duty of the occupier of premises, is an excellent illustration of this.^ More than a century ago, Burke observed that the practice of the law, though in his view " a science which does more to quicken and invigorate the understanding than all the other kinds of learn- ing put together," does not always, except in the highest order of intellects, " open and liberalize the mind " and is even apt to give a turn to " think the substance of business not to be much more im- portant than the forms in which it is conducted." Judged by this 1 Maxim Nordenfelt Gun & Ammunition Co. v. Nordenfelt, [1893I i Ch. 631. 2 18 Q. B. D. 694. 8 In Baroness Wenlock v. River Dee Co., 36 Ch. D. 684, Lord Bowen gave the best statement of general corporate powers to be found in the reports. In the course of a singularly lucid opinion, in Abrath v. Northeastern Ry. Co., 11 Q. B. D. 455, he simplified the use of the term " burden of proof." In Low v. Bouviere, [1891] 3 Ch. 105, he defined estoppel. In Steinman v. Angier Line, [1891] i Q. B. 621, he showed how the usual exceptions in a bill of lading '* limit the liability, not the duty." He summed up his view of the law applicable to contracts in restraint of trade in the fol- lowing terms in Maxim Nordenfelt Gun & Ammunition Co. v. Nordenfelt, [1893] i Ch. 631:- restraints wholly unlimited in area, are not, as a rule, permitted by the law, although the rule admits of exceptions. Partial restraints, or, in other words, restraints which in- volve only a limit of places at which, of persons with whom, or of modes in which, the trade is to be carried on, are valid when made for a good consideration, and where they do not extend further than is necessary for the reasonable protection of the covenantee. A limit in time does not, by itself, convert a general restraint into a partial one. * That which the law does not allow is not to be tolerated because it is to last for a short time only.' In considering, however, the reasonableness of a partial restraint, the time for which it is to be imposed may be a material element to consider."
 * The result seems to me to be as follows : General restraints, or, in other words,
