Also, if the summit of the mountain could not be reached on one side, and if, on the other, they could not get round the base of the cone, it would be impossible to survey the western part of the country, and their object in making the ascent would in part be altogether unattained.
Or, si la cime de la montagne ne pouvait être atteinte, d'une part, et si, de l'autre, on ne pouvait contourner la base du cône, il serait impossible d'examiner la portion occidentale de la contrée, et le but de l'ascension serait en partie manqué.
