Mr. T. S. Kennedy (of the firm of Fairbairn & Co.), whose practical acquaintance with mountaineering, and with the use and manufacture of tools, makes his opinion particularly valuable, has contrived the best that I have seen; but even it seems to me to be deficient in rigidity, and not to be so powerful a weapon as the more common kind with the fixed head. The simple instrument which is shown in the annexed diagram is the invention of Mr. Leslie Stephen, and it answers the purposes for which he devised it, namely, for giving better hold upon snow and ice than can be obtained from the common alpenstock, and for cutting an occasional step. The amateur scarcely requires anything more imposing, but for serious ice-work a heavier weapon is indispensable. To persons armed with the proper tools, ice-slopes are not so dangerous as many places which appeal less to the imagination. Their ascent or descent is necessarily laborious (to those who do the work), and they may therefore be termed difficult. They _ought_ not to be dangerous. Yet they always seem dangerous, for one is profoundly convinced that if he slips he will certainly go to the bottom. Hence, any man, who is not a fool, takes particular care to preserve his balance, and, in consequence, we have the noteworthy fact that accidents have seldom or never taken place upon ice-slopes. The same slopes covered with snow are much less impressive, and _may_ be much more dangerous. They may be less slippery, the balance may be more easily preserved, and if one man slips he may be stopped by his own personal efforts, provided the snow which over-lies the ice is consolidated and of a reasonable depth. But if, as is more likely to be the case upon an angle of 50° (or anything approaching that angle), there is only a thin stratum of snow which is not consolidated, the occurrence of a slip will most likely take the entire party as low as possible, and in addition to the chance of broken necks, there will be a strong probability that some, at least, will be smothered by the dislodged snow. Such accidents are far too common, and their occurrence, as a rule, may be traced to the want of caution which is induced by the apparent absence of danger. I do not believe that the use of the rope, in the ordinary way, affords the least _real_ security upon ice-slopes. Nor do I think that any benefit is derived from the employment of crampons. Mr. Kennedy was good enough to present me with a pair some time ago, and one of these has been engraved. They are the best variety I have seen of the species, but I only feel comfortable with them on my feet in places where they are not of the slightest use, that is in situations where there is no possibility of slipping, and would not wear them upon an ice-slope for any consideration whatever. All such adventitious aids are useless if you have not a good step in the ice to stand upon, and if you have got that, nothing more is wanted except a few nails in the boots.
