However, as these data are of con-siderable interest in themselves, they have been summarizedand are contained in Table LXIV. While the length of tracktested was but 916 ft. the results have been reduced to a basisof resistance per 1000 ft. of track in each case, as this is a moreconvenient figure for comparison.
