To reduce these several longitudes, and the latitude, to the Pic of Teneriffe, one of the most noted points of land with geographers (to obtain the true situation of which, I have entered into this particular discussion), I had recourse to the bearing, and a few hours of the ship’s run after leaving Santa Cruz road; and found it to be 12ʹ 11ʺ south of the road, and 29ʹ 30ʺ of longitude west of it. As the base, which helped to determine this, was partly estimated, it is liable to some error; but I think I cannot be much mistaken. Dr. Maskelyne, in his _British Mariner’s Guide_, places the Pic in the latitude of 28° 12ʹ 54ʺ. This, with the bearing from the road, will give the difference of longitude 43ʹ, which considerably exceeds the distance they reckon the Pic to be from Santa Cruz. I made the latitude of the Pic to be 28° 18ʹ north. Upon that supposition, its longitude will be as follows: { the time-keeper 17° 0ʹ 30ʺ } By { lunar observations 16° 30ʹ 20ʺ } west. { Mr. Varila 16° 46ʹ 0ʺ } But if the latitude of it is 28° 12ʹ 54ʺ, as in the _British Mariner’s Guide_, its longitude will be 13ʹ 30ʺ more westerly. The variation, when we were at anchor in the road, by the mean of all our compasses, was found to be 14° 41ʹ 20ʺ west. The dip of the north end of the needle was 61° 52ʹ 30ʺ. Some of Mr. Anderson’s remarks on the natural appearances of Teneriffe, and its productions; and what he observed himself, or learnt by information, about the general state of the island, will be of use, particularly in marking what changes may have happened there since Mr. Glas visited it. They here follow in his own words: “While we were standing in for the land, the weather being perfectly clear, we had an opportunity of seeing the celebrated Pic of Teneriffe. But, I own, I was much disappointed in my expectation with respect to its appearance. It is, certainly, far from equalling the noble figure of Pico, one of the western isles which I have seen; though its perpendicular height may be greater. This circumstance, perhaps, arises from its being surrounded by other very high hills; whereas Pico stands without a rival. “Behind the city of Santa Cruz, the country rises gradually, and is of a moderate height. Beyond this, to the south westward, it becomes higher, and continues to rise towards the Pic, which, from the road, appears but little higher than the surrounding hills. From thence it seems to decrease, though not suddenly, as far as the eye can reach. From a supposition that we should not stay above one day, I was obliged to contract my excursions into the country; otherwise, I had proposed to visit the top of this famous mountain.[82]
