V/e believe that such exporimonts can bo ex pected to furnish asnwors to the questions which you have outlined. The estimated cost of $5,OChnnually for a poriod of three years, making a total of $15,000, is correct. Your suggestion to make advanced quarterly payments of $1,250 will bo entirely satisfactory to the Laboratory. If thl3 is not convenient any other arrangcr^nt that you may care to make will bo acceptable. : of thoso and thut npprovul Tho Saranac Laboratory agrees thut tho results studies 'shall become tho property of tho contributors ' thus manuscripts of any reports shull bo submitted fer of the contributors before publication v--'v.l-` I would rocccmnr.d that tho experiments bo 'performed with cure Canadian antes tos' fibre' containing re latively llttlo aev.rentir.e i'uck oust.'' Tho "Kings Floats" ujul in our first experiment was unsatlsfactory owing to tho fact that It contained such a high concontratian- of non- fltrcus rock dust.__If this moots with your approval I would suggest that a sample bo 'submitted to the Laboratory for chonlcal and petrographic analysis. .- .
