"It is impossible," answered Zerina; "as you live in air, so they live in fire; if you were to be taken out of your peculiar element, you would languish and droop; in the same manner, if you were to transport them into your element, they would perish."
"Only look," said Maria, "how happy and joyous they seem; listen how they shout and sing."
"Below," said her little friend, "the fire-streams spread in every direction throughout the whole earth, imparting heat to the vegetation, and ripening the seed, till it shoots upward into a fruitful plant: hence you have your flowers and fruits. These fire-streams go side by side with the water-streams; and to their mutual agency you owe all the herbage of your pasture-land, all the beauties of your flower-garden, all the luscious produce of your orchards: they are your great benefactors: without them your present fruitful land would be a desolate wilderness; your flower-gardens overrun with noxious weeds, and your orchard-trees blighted and dying away. In consequence of such benefits resulting from them, they are ever active, ever happy. But this heat is too great for a child of air; come, let us return to the garden."
There had been a great change in the atmosphere; the moonshine lay on all the flowers, the birds were hushed, and the children were slumbering on the greensward.
"Happy, holy calmness," thought Maria; "Peace has certainly chosen her retreat in these lovely regions; Contentment is linked with her; and wherever they roam hand in hand, all is joy, all is tranquillity."
But did Maria slumber? No; she and her little friend felt no weariness; they roamed through the live-long summer night amid the groves and sylvan avenues, prattling in youthful eloquence on the wondrous spectacles that were before them. At day-break they refreshed themselves with fruits and milk; and Maria said to her little companion, "Let us go out to the fir-trees yonder; it will be a change for us."
"With all my heart," said Zerina; "then you can see our sentries at the same time, and they will be sure to please you. They take their stand upon the rampart between the trees."
They walked on through the flower-garden, through beautiful thickets peopled with nightingales; then they mounted the vine-hills, and following the course of a clear crystal stream in its winding channel, they arrived at the firs, and the high ground that formed the boundary of the district.
"How is it," said Maria, "that we have had such a long walk to reach the firs here within, when the circuit on the outside is so small?"
"I cannot say how it is," said the other; "but so it is."
