We struck camp at Pakihi early on the following day, but had some difficulty in crossing the Mangawhero, which we found to be a broad, rapid, boulder-strewn stream. The banks were very steep and slippery, and when we had our horses down on one side we had great difficulty in getting them up the other.
As we got again into the thick of the forest the vegetation became denser, and the _rimu_-trees, seeming to increase in size, shot up for over a hundred feet as straight as gun-barrels. Where some of these giants of the forest had fallen across our track, we had often to cut a way round them for our horses, through the thick shrub and tangled vines, the latter of which impeded our progress at every turn, by tripping us up, and winding round the legs and necks of our animals like treacherous snares. The enormous _rata_-vines had been very troublesome up to this point, but now we had to do battle not only against them, but against the supple-jacks, which we found growing everywhere in a perfect network of snakelike coils on the soft, marly soil of the country we were now in. It was nothing to have a supple-jack round the neck and a _rata_-vine round the legs at the same time, while our horses would often get so entangled that they would refuse to move until we had cut them a clear passage out of their difficulties.
In many instances, owing to surrounding obstacles, there was no alternative but to make them leap over the fallen trees in our way, and when not able to do this, the animals would jump on to them and leap down like dogs. Indeed, the tricks that they had to go through to get over these and other impediments rendered them almost as clever as circus-horses.
Another frequent feature we noticed was that where the great trees had apparently been lying for some time, the seeds of other trees had fallen upon them, and, germinating into life, had sent their roots down into the very heart of these decaying vegetable monsters. In this way it was no uncommon sight to see three or four different species of large trees living and flourishing upon the dead trunks of these forest giants.
We crossed the Mangatotara River twice, and after passing through a very rough and broken portion of the great wilderness, we fell in with another river, called the Mangatuku, and which we had to cross three times in its winding course. Both of these streams appeared to drain a large area of country, and so dense was the vegetation along their banks that it was only here and there that a ray of sunlight shot through the thick canopy of green upon them.
