If the forest is all cleared away, almost all the insects disappear with it; but when small clearings and paths are made, the fallen trees in various stages of drying and decay, the rotting leaves, the loosening bark and the fungoid growths upon it, together with the flowers that appear in much greater abundance where the light is admitted, are so many attractions to the insects for miles around, and cause a wonderful accumulation of species and individuals.

When the entomologist can discover such a spot, he does more in a mouth than he could possibly do by a year's search in the depths of the undisturbed forest.
The next morning we left early, and reached the mouth of the little river in about au hour.

It flows through a perfectly flat alluvial plain, but there are hills which approach it near the mouth.

Towards the lower part, in a swamp where the salt-water must enter at high tides, were a number of elegant tree-ferns from eight to fifteen feet high.
These are generally considered to be mountain plants, and rarely to occur on the equator at an elevation of less than one or two thousand feet.

In Borneo, in the Aru Islands, and on the banks of the Amazon, I have observed them at the level of the sea, and think it probable that the altitude supposed to be requisite for them may have been deduced from facts observed in countries where the plains and lowlands are largely cultivated, and most of the indigenous vegetation destroyed.
Such is the case in most parts of Java, India, Jamaica, and Brazil, where the vegetation of the tropics has been most fully explored.
Coming out to sea we turned northwards, and in about two hours' sail reached a few huts, called Langundi, where some Galela men had established themselves as collectors of gum-dammar, with which they made torches for the supply of the Ternate market.
