The rain making experiments which took place some time ago at McCook Field have just been resumed at Bolling Field, Anacostia, D. C. On Oct. 29, last, two Air Service pilots, Capt. A. I. Eagle and Lieut. W. E. Melville, using the electrified sand process devised by Dr. L. Francis Warren of Harvard University, successfully “shot down” a series of clouds which overshadowed the field.
