Many are scattered, as if by an eruption; others lie in slab or dome shape upon the shore. In the few cuttings of the higher levels I afterwards remarked that detached 'hardheads' are puddinged into the friable laterite; but I nowhere found the granitic floor-rock protruding above ground.

The Ilongots, poor chaps, had done their best with it, and the labor of construction must have been fearful. But the footing was nothing but volcanic mud, laterite, all the worse from a recent rain. Our ponies sank over their fetlocks at every step, and required constant urging to move at all. Compared to the one I was riding, Bubud was a race-horse!

The dark red clay soil, dried almost to the consistency of laterite, cannot be loosened by rain or sun, and in places it is hardened like that of Brazilian Porto Seguro, where the people complain that they cannot bury their dead. All the uplands, however, grow grass which is sometimes ten to twelve feet tall, and in places there are shrubs and trees.

They are of all sizes, from a rope to a cable multiplied a thousandfold; and they stand out in boldest dado-relief where the soft background of tufa, or laterite, has been crumbled away by rain and storm-blast. Some writers have described them as ramifying like a tree and its branches, and crossing and interlacing like the ties of a building; as if sundry volcanic vents had a common centre below.

The 'sandy beach' has been waked from its longaeval placidity. Trains of bullock-carts are lumbering along new-made tracks, bringing stone and laterite and bricks and timber from various centres; and endless files of coolies, with baskets on their heads, are bringing sand from the summer-dry edges of the bed of the Cooum river.

When all the angular fragments are of volcanic rocks the mass is usually termed a volcanic breccia. Laterite is a red or brick-like rock composed of silicate of alumina and oxide of iron. The red layers called "ochre beds," dividing the lavas of the Giant's Causeway, are laterites. These were found by Delesse to be trap impregnated with the red oxide of iron, and in part reduced to kaolin.

These red bands are sometimes prismatic, the small prisms being at right angles to the sheets of lava. Red clay or red marl, formed as above stated by the disintegration of lava, scoriae, or tuff, has often accumulated to a great thickness in the valleys of Madeira, being washed into them by alluvial action; and some of the thick beds of laterite in India may have had a similar origin.

Running the eye west of the Battery, a few wooden houses or sheds, some of them overhanging the dwarf cliff, the black rocks, and the red-yellow sands, lead to Taylor's warehouses, a huge pile of laterite still unfinished. Here the traditional 'man and boy' may sometimes be seen working in the cooler and more comfortable hours.

The colours of the houses are various; plain white is rare, and the prevailing tints are the light-brick of the fresh laterite and the dark rusty ochre of the old. But all are the same in one point, the mildewed, cankered, gangrened aspect, contrasting so unfavourably with the whitewashed port-towns of the Arabs.

Banca, on the other hand, agrees with Malacca, Singapore, and the intervening island of Lingen, in being formed of granite and laterite; and these have all most likely once formed an extension of the Malay peninsula.
