On tinted paper very nice effective sketches may be made with one tube of sepia and a cake of Chinese white. With these we should advise three brown sable pencils in flat German silver ferrules--Nos. 1, 3, and 6. With the addition to these of the three primitive colours--red, blue, and yellow--a considerable range of subjects may be painted; indeed could we obtain these in perfect purity, we should require no other. But, as this is impossible, we subjoin a list of colours, placing first in order those that we have found most useful (Chinese white and sepia have been already mentioned):--
Indian yellow, Carmine, French blue, Yellow ochre, Light red, Prussian blue, Gamboge, Rose madder (perhaps in cake), Cobalt, Raw sienna (cake), Burnt sienna, Indigo, Yellow lake, Mars orange, Payne's grey, Vermilion (cake), Vandyke brown, Emerald green, Scarlet lake (cake), Crimson lake, Purple lake, Cadmium yellow (cake), Brown madder (cake), Purple madder (cake).
With these, the whole set from 1 to 6 of the sables in flat albata will be needed, and we advise two each of 1, 2, and 3, as well as one or two large swans' quills for washing in the sky or flat tints. A tripod sketching stool folding to the size of a special's staff would be useful, but the rivet should be strong and well clinched. Let the watercolour box have divisions on the edge of the palette for every colour it contains. If you take an easel, do not trust an india-rubber collar joint; it will not stand tropical heat; let the joint be brass. The tripod easel, folding up like a single rod, is most portable. We have in this said nothing of oil colours; amateurs will hardly need them in a wild country; but when we treat more at length on this subject our own equipment will be given.
If the traveller aims at exploring and approximately mapping the country he passes through, astronomical instruments are indispensable, and of these none are more useful than the compass; the sextant, with artificial horizon; the note book, conveniently ruled, for recording observations; and the protractor, the scale, and the dividers, for laying them down upon the map. If merely a pleasure excursion in a sufficiently known country is contemplated, a pocket compass will be all that is needed; and even that is dispensed with by hunters and traders, who push farther every year into the wilderness without fear of either mistaking their way or being unable to return upon their own tracks.
