Joseph says: "We know that the angels were our companions, for we saw them." A circumstance in the experience of Parley P. Pratt furnishes further testimony of the presence of angels with this expedition. Elder Pratt was chiefly engaged as a recruiting officer, and on one occasion, when he had traveled all night to overtake a small company he was conducting to the main camp, he stopped at noon on a broad level plain to let his horse feed. No habitation was near. Stillness and repose reigned around him. "I sank down," he says, "overpowered with a deep sleep, and might have lain in a state of oblivion till the shades of night had gathered about me, so completely was I exhausted for the want of sleep and rest; but I had only slept a few moments till the horse had grazed sufficiently, when a voice, more loud and shrill than I had ever before heard, fell upon my ear, and thrilled through every part of my system; it said: _'Parley, it is time to be up and on your journey.'_ In the twinkling of an eye I was perfectly aroused, I sprang to my feet so suddenly that I could not at first recollect where I was, or what was before me to perform. I afterwards related the circumstance to Brother Joseph Smith, and he bore testimony that it was the angel of the Lord who went before the camp, who found me overpowered with sleep, and thus awoke me." [B] [Footnote B: Autobiography of Parley P. Pratt, p. 123.] The line of march led the camp through Indiana and the central part of Illinois. The journey was undertaken, too, at a time of year--May and June--when nature appears in her most lovely attire--when the forests were in full leaf, and filled with the resonance of birds, the hum of bees and insects; when the great prairies, which quite bewilder one with their vastness, are clothed in their variegated garments of grass and wild flowers; at a time of year when in the upper deep there is a deeper blue, when the rising sun seems to shed a brighter light upon the earth beneath, and when his parting rays paint the evening skies in splendors unsurpassed.[C] [Footnote C: PEN-PICTURE OF THE CAMP.--In fancy I see them after a hard day's march making their encampment. The sun has just sunk behind the western horizon as Joseph and the standard bearer are choosing the place for their night's encampment They have paused on the summit of one of the gentle swells of prairie so common in their line of travel. A short distance to the south is a small wooded stream. To the north and east, as far as the eye can see, is nothing but the broad, rolling prairie; looking west, the horizon is bounded by a view of the heavy forests which marked the meandering course of the Illinois.
