The party had not long before passed through a beautiful country. The narrative says:--"During the earlier part of the day our ride had been over a very level prairie, or rather a succession of long stretches of prairie, separated by lines and groves of oak timber, growing along dry gullies, which are tilled with water in seasons of rain; and perhaps, also, by the melting snows. Over much of this extent the vegetation was spare; the surface showing plainly the action of water, which, in the season of flood, the Joaquin spreads over the valley. About one o'clock, we came again among innumerable flowers; and, a few miles further, fields of beautiful blue-flowering _lupine_, which seems to love the neighbourhood of water, indicated that we were approaching a stream. We here found this beautiful shrub in thickets, some of them being twelve feet in height. Occasionally, three or four plants were clustered together, forming a grand bouquet, about ninety feet in circumference, and ten feet high; the whole summit covered with spikes of flowers, the perfume of which is very sweet and grateful. A lover of natural beauty can imagine with what pleasure we rode among these flowering groves, which filled the air with a light and delicate fragrance. We continued our road for about half a mile, interspersed through an open grove of live oaks, which, in form, were the most symmetrical and beautiful we had yet seen in this country. The ends of their branches rested on the ground, forming somewhat more than a half sphere of very full and regular figure, with leaves apparently smaller than usual. The Californian poppy, of a rich orange colour, was numerous to-day. Elk and several bands of antelope made their appearance. Our road now was one continued enjoyment; and it was pleasant riding among this assemblage of green pastures, with varied flowers and scattered groves, and, out of the warm, green spring, to look at the rocky and snowy peaks where lately we had suffered so much."
