San Lois Obispo, Cal. Lancaster, Pa. The burying operation will require about four aonth*. At the end of on* year, one piece from each teat will be taken up at each location, and the condition of the pipe at that tlae will determine how soon the other pleee* will be taken up for examination. The red lead paint used this year In the A. P. I. test con formed aore to recommends! practice than the red lead paint that was used last year in the A. 0. A. tests. In that it contained mere oil, lee* turpentine, and possessed a higher true red lead content. Both variations rare, however, selected because of the ease with which they could be compounded and applied though a formula elallar to the on* given ebov* wllfe rroa on* to three quarts of linseed ell replaced by turpentine would be a more satisfactory compromise for the varying condition* which must be met. * **? - "'I'll** m ij ib il a I Our object in cooperating with the Aaerican Gae Aaeociation end American Petroleua Inatitute in their reepectiTe research pregrane, is, of course, to dewelop a coftparatirely new outlet for a lead product.
