The following hints, it is presumed, may serve to direct & facilitate such enquiries.
Distant sea views of Islands & Continents, as they present a general idea of their rise elevation & vertical outline, ought to be correctly delineated, not merely for the information of the Geologist, but for the advantage of the Navigator.
On a nearer approach, the more particular features of this outline unfold themselves. The mass of high ground then gradually divides itself into ridges, which successively develope their distinct features & arrange themselves under a proportional Scale of heights, the highest ridge being most probably at the greatest distance from the sea shore.
This different aspect of the Country must be markd [marked] by an accurate drawing.
Mountains of a Volcanic origin may be distinguishd [distinguished] at a great distance by their invariable tendency to assume a conical form, by their insulated position in respect to other mountains which are usualy [usually] connected together in the form of ridges, by the smoke which they emit & by the general redness of their tints.
Mountains of this description abound in curious subject for drawings, but those which are selected by the Naturalist are not in general such as would satisfy the Artist or the Connoisseur for they are not the most picturesque.
The points of view which are most characteristical of the volcanic phoenomena will be chosen as indeed they ought to be for a Voyage which is devoted to the purposes of Science and the Artist
