On going away, Billy and I took a run up the canyon. Billy was in high spirits, and went racing up the narrow road, winding and turning through the chaparral, brushing me against the the stiff scrub oak and loping under low branches so fast that the sharp leaves snapped back, stinging my cheeks. We had a gay ride, with a spice of excitement thrown in; for on our way home, in the thick dust across our path, besides the pretty quail tracks that made wall-paper patterns on the road, were the straight trails of gopher snakes, and the scalloped one of a rattlesnake we had been just too late to meet.

At our next session with the blue-grays, when she was on the nest, her mate came back to relieve her and cried in his quick cheerful way, "Here I am, here I am!" Either she was taking a nap or didn't want to stir, for she didn't budge till he called insistently, "Here I am, here I am!" Then he hopped down in her place, and raising his head above the nest, remarked again, as if commenting upon the new situation, "Here I am!"

It was quite a different matter when she came back to work. She only called "hello," not even hinting that he should make way for her, but he hopped off at the first sound of her voice, flying away promptly to another tree and calling back like a gleeful boy let out of school, "Here I am!"

She was no more eager to go to the nest than he, however, and once when she came flirting leisurely along from twig to twig, she stopped a long time on the edge of the nest and leaned over, presumably to arrange the eggs; perhaps she and her mate had different views as to their proper positions. The next time I visited the gnats, she acted as if she really could not make up her mind to settle down to brooding on such a beautiful morning. The fog had cleared away and the air was fresh and full of life; goldfinches and lazuli buntings were singing merrily, and light-hearted vireos were shouting chick-a-de-chick'-de-villet' from the brush. How much pleasanter it would be for such an airy fairy to go off for a race with her mate than to settle down demurely tucked into a cup! "Tsang," she cried impatiently as she flew up to catch a fly. She flirted about the branches, whipped up in front of the nest, couldn't make up her mind to go in, and flounced off again. But the eggs would get cold if she didn't cover them, so back she came, hopped up on the edge of the nest, and stood twisting and turning, glancing this way and that as though for a fly to chase, till she happened to look down at the eggs; then she whipped her tail, dropped in and—jumped out again!

During the morning when she was away and her mate was waiting for her to come back to 'spell' him, he too got impatient. He hopped out of the nest crying, "Now here I am, quick, come quick!" and as he flew off, sang out in his funny little soliloquizing way, "Well, here I go; here I go!"

His restless spouse had only just settled down when a wren-tit—a wren-like bird with a long tail—flew into a bush near her oak, and she darted out of the nest to snap her bill over his head. I thought it merely an excuse to leave her brooding. Calling out "tsang," she again flew at the brown bird who was hopping around in the bush, so innocently, as I thought. Conqueror for the moment, she flaunted back to the nest, and after much ado finally settled down.

For a time all was quiet. Hearing the low cooing of doves, I went to talk to the pretty bird in the oak, and she let me come near enough to see her bluish bill and quiet eyes. As I returned to the gnatcatchers, a chewink was hoeing in the sand stream. Again the wren-tit approached stealthily. I watched with languid interest till he got to the gnat's tree. The instant he touched foot upon her domain, she dashed down at him, crying loudly and snapping her bill in his face. The brown bird dodged her blows, held his footing in spite of her, and slowly made his way up to the nest. I was astonished and frightened. He leaned over the nest, and—what he actually did I could not see, for by that time the blue-gray's cries had called her mate and they were both screaming and diving down at him as if they would peck his eyes out; and it sounded as if they hit him on the back good and hard.

A peaceful lazuli bunting, hearing the commotion, came to investigate, but when she saw what was happening held back against the side of a twig as though afraid of getting struck, and soon flew off, having no desire to get mixed up in that affray.

When the wren-tit had at last been driven from his position, the gnatcatchers flew up into a tree and, standing near together, talked the matter over excitedly. Then one of them went back to the nest, reached down into it and brought up something that it appeared to be eating. Its mate went to the nest and did the same, after which one of them flew away with a broken eggshell. When the little creatures turned away from the plundered nest they broke out into cries of distress that were pitiful to hear. I felt indignant at the wren-tit. How could a bird with eggs of its own do such a cruel thing? But then, I reflected, we who pretend to be better folks than wren-tits do not always spare our neighbors because of our own troubles. When the poor birds had carried away their broken eggshell, one of them came and tugged at the nest lining till it pulled out a long horsehair and what looked like a feather, apparently trying to take out everything that the egg had soiled.

When the little housekeeper was working over her nest, a brown towhee flew into the tree. On the instant there was a flash of wings—the gnat was ready for war. But after a fair look at the big peaceful bird, she flew to the next tree without a word—she evidently knew friends from enemies. I never liked the towhee so well before. But though the blue-gray had nothing to say against her neighbor sitting up in the tree if he chose, her nerves were so unstrung that when she lit in the next tree she cried out "tsang" in an overburdened tone. It sounded so unlike the usual cry of the light-hearted bird, it quite made me sad.
