Fortunately, when Godfrey reached the first line of shrubs he recognized two sorts of fruits or roots. One sort had to pass through the fiery trial before being eaten, the other was edible in its natural state. Of these two vegetables the American Indians make constant use. The first was a shrub of the kind called "camas," which thrives even in lands unfit for culture. With these onion-like roots, should it not be found preferable to treat them as potatoes, there is made a sort of flour very rich and glutinous. But either way, they have to be subjected to a certain cooking, or drying. The other bush produces a species of bulb of oblong form, bearing the indigenous name of "yamph," and if it possesses less nutritive principles than the camas, it is much the better for one thing,--it can be eaten raw. Godfrey, highly pleased at his discovery, at once satisfied his hunger on a few of these excellent roots, and not forgetting Tartlet's breakfast, collected a large bundle, and throwing it over his shoulder, retook the road to Will Tree. That he was well received on his arrival with the crop of yamphs need not be insisted on. The professor greedily regaled himself, and his pupil had to caution him to be moderate. "Ah!" he said. "We have got some roots to-day. Who knows whether we shall have any to-morrow?" "Without any doubt," replied Godfrey, "to-morrow and the day after, and always. There is only the trouble of going and fetching them." "Well, Godfrey, and the camas?" "Of the camas we will make flour and bread when we have got a fire." "Fire!" exclaimed the professor, shaking his head. "Fire! And how shall we make it?" "I don't know yet, but somehow or other we will get at it." "May Heaven hear you, my dear Godfrey! And when I think that there are so many fellows in this world who have only got to rub a bit of wood on the sole of their boot to get it, it annoys me! No! Never would I have believed that ill-luck would have reduced me to this state! You need not take three steps down Montgomery Street, before you will meet with a gentleman, cigar in mouth, who thinks it a pleasure to give you a light, and here--" "Here we are not in San Francisco, Tartlet, nor in Montgomery Street, and I think it would be wiser for us not to reckon on the kindness of those we meet!" "But, why is cooking necessary for bread and meat? Why did not nature make us so that we might live upon nothing?" "That will come, perhaps!" answered Godfrey with a good-humoured smile. "Do you think so?" "I think that our scientists are probably working out the subject." "Is it possible! And how do they start on their research as to this new mode of alimentation?"
