O rainbow of the battle-storm! Methinks thou'rt gleaming on my sight; I see thy fair and fragile form Amid the thick cloud of the fight. SARA J. CLARKE. One grain of incense with devotion offered, Is beyond all perfumes or Sabaean spices. MASSINGER. The following incident, we are informed by Mrs. Ellet, was communicated to a minister--Rev. J. H. Saye--by two officers in the Revolutionary war. One of them was in the skirmish referred to; the other lived near the scene of action; hence, it may be relied on as authentic. The name of the heroine is unknown, which is greatly to be regretted: "Early in the war, the inhabitants on the frontier of Burke county, North Carolina, being apprehensive of an attack by the Indians, it was determined to seek protection in a fort in a more densely populated neighborhood in an interior settlement. A party of soldiers was sent to protect them on their retreat. The families assembled, the line of march was taken towards their place of destination, and they proceeded some miles unmolested--the soldiers marching in a hollow square, with the refugee families in the centre.

Still they fought on, determined on the destruction of the victims who offered such desperate resistance. All at once an appalling sound greeted the ears of the women and children in the centre; it was a cry from their defenders--a cry for powder! 'Our powder is giving out,' they exclaimed. 'Have you any? Bring us some, or we can fight no longer!' A woman of the party had a good supply. She spread her apron on the ground, poured her powder into it, and going round, from soldier to soldier, as they stood behind the trees, bade each who needed powder put down his hat, and poured a quantity upon it. Thus she went round the line of defence, till her whole stock, and all she could obtain from others, was distributed. At last the savages gave way, and, pressed by their foes, were driven off the ground. The victorious whites returned
