" ''A Study of Size of Diamonds in Diamond Drilling' is the research problem which will be discussed in this treatise.
The author's interest in the effect of size of diamonds was created by Mr. R. D. Longyear of the E. J. Longyear Company of Minneapolis, Minnesota. Mr. Longyear, when asked for suggestions for a research problem concerning diamond drilling suggested, among other things, that there was a need for further work on the factor of size of stones. After extensive reading and reviewing, the author learned that many investigators had recognized changes in results attributable to changes in size of stones, but that few had conducted scientific or organized research directed primarily toward analyzing this proposition.
The next step was to determine if the subject were of enough consequence to warrant further study. Correspondence with several manufacturers and investigators stressed the importance and enhanced the interest in the research. It then was decided to pursue this work if the equipment could be obtained"--Introduction, page 1.
