[83] Professor Forbes gives the bearing of the Cervin from the top of the Riffelhorn as 351 deg., or N. 9 deg. W., supposing local attraction to have caused an error of 65 deg. to the northward, which would make the true bearing N. 74 deg. W. From the point just under the Riffelhorn summit, _e_, in Fig. 78, at which my drawing was made, I found the Cervin bear N. 79 deg. W. without any allowance for attraction; the disturbing influence would seem therefore confined, or nearly so, to the summit _a_. I did not know at the time that there was any such influence traceable, and took no bearing from the summit. For the rest, I cannot vouch for bearings as I can for angles, as their accuracy was of no importance to my work, and I merely noted them with a common pocket compass and in the sailor's way (S. by W. and 1/2 W. & C.), which involves the probability of error of from two to three degrees on either side of the true bearing. The other drawing in Plate +38+ was made from a point only a degree or two to the westward of the village of Zermatt. I have no note of the bearing; but it must be about S. 60 deg. or 65 deg. W. [84] Independent travellers may perhaps be glad to know the way to the top of the Riffelhorn. I believe there is only one path; which ascends (from the ridge of the Riffel) on its eastern slope, until, near the summit, the low but perfectly smooth cliff, extending from side to side of the ridge, seems, as on the western slope, to bar all farther advance. This cliff may, however, by a good climber, be mastered even at the southern extremity; but it is dangerous there: at the opposite or northern side of it, just at its base, is a little cornice, about a foot broad, which does not look promising at first, but widens presently; and when once it is past, there is no more difficulty in reaching the summit. [85] I ought before to have mentioned Madame de Genlis as one of the few writers whose influence was always exerted to restore to truthful feelings, and persuade to simple enjoyments and pursuits, the persons accessible to reason in the frivolous world of her times. [86] Veillees du Chateau, vol. ii. [87] The actual extent of the projection remaining the same throughout, the angle of suspended slope, for that reason, diminishes as the cliff increases in height.
