Australia Felix - September 14 - Surveyor's Peak Mystery Cache

The given coordinates are for the Mt Abrupt Geodetic Survey Triangulation Station (Trig Point) located on it's summit.
To find the location of the cache however you will need to visit a monument to Major Mitchell erected in Dunkeld at S37° 38.974 E142° 20.694 and answer the following questions;

The number of letters in the 3rd line of the original inscription = A
The total number of letters in the first 5 lines of the original inscription on the monument = B
The cache can be found at A/3 metres x bearing B° true from the Trig Point

The one litre sistema container that originally contained a log book with pen an assortment of swaps and a Geocoin.
Please trade fairly and ensure you leave the cache well covered to prevent casual discovery.

I was most anxious to ascend Mount Abrupt, the first peak to the northward of Mount Sturgeon, that I might close my survey of these mountains and also reconnoitre the country before us. This morning clouds hung upon the mountains however, and I could scarcely indulge a hope that the weather would be favourable for the purposed survey; nevertheless I bent my steps towards the mountain, having first set the carpenter to work to make an additional width of felloe to the narrow wheels of one of the carts, that it might pass with less difficulty over soft ground. We soon came to a deep stream flowing not FROM but apparently TOWARDS the mountains; its general course being westward. It was so deep that our horses could scarcely ford it without swimming. Reeds grew about and the bottom was soft, although two kinds of rock appeared in its banks. On the right was trap, on the left the ferruginous sandstone of which all these mountains consist. We soon entered on the barren and sandy but firm ground at their base which, with its peculiar trees and shrubs, appeared so different from the grassy plains. The banksia, the casuarina, and the hardy xanthorrhoea reminded us of former toils on the opposite side of these ranges.

VIEW OF THE GRAMPIANS FROM THE SUMMIT.

The weather turned out better than I had expected, and from the summit of Mount Abrupt I beheld a truly sublime scene; the whole of the mountains, quite clear of clouds, the grand outline of the more distant masses blended with the sky, and forming a blue and purple background for the numerous peaks of the range on which I stood, which consisted of sharp cones and perpendicular cliffs foreshortened so as to form one grand feature only of the extensive landscape, though composing a crescent nearly 30 miles in extent: this range being but a branch from the still more lofty masses of Mount William which crowned the whole. Towards the coast there was less haze than usual, for I could distinguish Lady Julia Percy's Isle which I had looked for in vain from Mount Napier, a point twenty-four miles nearer to it. Here I could also trace the course of the stream we had crossed that morning from its sources under the eastern base of the mountains to a group of lower hills twenty-seven miles distant to the westward; which hills, named by me Dundas group, formed a most useful point in my trigonometrical survey.

LAKES.

Several extensive lakes appeared in the lowest parts adjacent; but what interested me most after I had intersected the various summits was the appearance of the country to the eastward, through which we were to find our way home. There I saw a vast extent of open downs and could trace their undulations to where they joined a range of mountains which, judging by their outlines, appeared to be of easy access. Our straightest way homewards passed just under a bluff head about fifty miles distant, and so far I could easily perceive a most favourable line of route by avoiding several large reedy lakes. Between that open country and these lakes on one side and the coast on the other, a low woody ridge extended eastward; and by first gaining that I hoped we should reach the open ground in a direction which should enable us to leave all the lakes on our left.

The largest pieces of water I could see were Lake Linlithgow and its companion in the open grassy plains between the range and Mount Napier, as previously discovered from that hill. Several small and very picturesque lakes, then as smooth as mirrors, adorned the valley immediately to the westward of the hill I was upon. They were fringed with luxuriant shrubs so that it was really painful to me to hurry, as I was then compelled to do, past spots like these, involving in their unexplored recesses so much of novelty amidst the most romantic scenery. The rock consisted of a finely-grained sandstone as in other parts of that mass. The Grampians of the south consist of three ranges covering a surface which extends latitudinally 54 miles and longitudinally 20 miles. The extreme eastern and highest summit is Mount William, in height 4,500 feet above the sea. The northern point is Mount Zero, in latitude 36 degrees 52 minutes 35 seconds South, and the southern is Mount Sturgeon, in latitude 37 degrees 38 minutes 00 seconds. I here again recognised the outline of the most northern and elevated range extending from Mount William to Mount Zero, but it was not so steep on the southern as on the northern side.

VICTORIA RANGE AND THE SERRA.

From this hill two other ranges branch off to the south; the western being marked Victoria range on the map, the eastern, the Serra, from its serrated appearance, the broken outlines they present being highly ornamental to the fine country around. On the northern slopes of the range are some forests of fine timber but in general the higher summits are bare and rocky. The chief source of the Glenelg is between the Victoria range and the most northern, whence it soon sinks into a deep glen or ravine, receiving numberless tributaries from other dells intersecting the adjacent country. A considerable branch of the Glenelg named by the natives the Wannon has its sources in the eastern and southern rivulets from these mountains. The waters falling northward enter the Wimmera, a different river whose estuary has not yet been explored. Returning towards the camp, on approaching the stream, we met with one of the most strikingly beautiful species of the common genus Pultenaea; its narrow heath-like leaves were so closely covered with soft silky hairs as to have quite a silvery appearance and the branches were loaded with the heads of yellow and brown flowers now fully open. It formed a new species of the Proliferous section, allied to Pultenaea stipularis.
