Climbers are absolutely incapable of any sustained effort when they reach certain altitudes, and the limit depends on the individual. It is the misfortune of some to feel an uncomfortable perturbation of the heart when once a definite level is passed. They are well enough able to exert themselves below that level, but can hope for no pleasurable exercise above it. With every desire to climb, with muscle and mind enough to excel in the sport, they are nevertheless debarred from enjoying the high Alps. Let them therefore make the best of our British hills for a while, and then perhaps proceed to the Dolomites in the Austrian Tyrol for fuller applications at a safe low level of what they have here learnt. Solitary scrambling is universally condemned. Most climbers of experience have learnt something about it, and are unanimous in their unfavourable judgment. Nothing teaches the scrambler so quickly, if his nerve is sufficiently strong; but the penalty paid for slight mistakes is often extreme, and the risk is too great for him to be justified in deliberately choosing the single-handed venture. A party of two makes the strongest combination for most of the ordinary Cumberland climbs; three are generally better for the severest courses. Any beyond that number will to a greater or less extent increase the difficulty of the ascent and the time spent in effecting it. A rough classification is here appended of over a hundred well-known courses judged under good conditions. They are divided into four sets. The first are easy and adapted for beginners, the second set are moderately stiff, those of the third set rank as the difficult climbs of the district, and the last are of exceptional severity. Some attempt has been made to arrange them in their order of difficulty, the hardest ones coming last; but the variations of condition of each due to wind, temperature, rain, snow, or ice are so extensive that no particular value should be attached to the sequence. But even if only approximately correct, the lists may help men in deciding for themselves where to draw the line that shall limit their own unaided performances. As for the items in the fourth class, they are best left alone. Mark the well-known words of an expert (Mr. C. Pilkington): ‘The novice must on no account attempt them. He may console himself with the reflection that most of these fancy bits of rock-work are not mountaineering proper, and by remembering that those who first explored these routes, or rather created them, were not only brilliant rock gymnasts but experienced and capable cragsmen.’ _Easy Courses._ Deep Ghyll, by the west wall traverse.
