On perfectly clear and quiescent summer nights on the plains of my native Banat, the stars are intensely bright and the sky looks black by contrast. “Thy hair is as black as the sky of a summer midnight” is a favorite saying of a Serbian lover to his lady-love. On such nights we could not see our grazing oxen when they were more than a few score of feet from us, but we could hear them if we pressed our ears close to the ground and listened. On such nights we boys had our work cut out for us. We were placed along a definite line at distances of some twenty yards apart. This was the dead-line, which separated the pasture-lands from the corn-field territory. The motto of the French at Verdun was: “They shall not pass!” This was our motto, too, and it referred equally to our friends, the oxen, and to our enemies, the Rumanian cattle-thieves. Our knife-blades were deep in the ground and our ears were pressed against the handles. We could hear every step of the roaming oxen and even their grazing operations when they were sufficiently near to the dead-line. We knew that these grazing operations were regulated by the time of the night, and this we estimated by the position of certain constellations like Orion and the Pleiades. The positions of the evening star and of the morning star also were closely observed. Venus was our white star and Mars was called the red star. The Dipper, the north star, and the milky way were our compass. We knew also that when in the dead of the night we could hear the faint sound of the church-bell of the Rumanian settlement about four miles to the east of us, then there was a breeze from the corn-fields to the pasture-lands, and that it carried the sweet perfume of the young corn to the hungry oxen, inviting them to the rich banquet-table of the corn-fields. On such nights our vigilance was redoubled. We were then all eyes and ears. Our ears were closely pressed to the ground and our eyes were riveted upon the stars above. * * * * *
