What reading level is Geological Survey of Hokkaido Report of Progress of the Yesso Geological Survey book?
To quickly assess the difficulty of the text, read a short excerpt:
-Iuagaki, aided by Mr. Saito, 13 Mr. Shi mad a drew, under my guidance the six cross sections of rock structure and reduced them to columnar sections of the rock beds, afterwards combining them into one. The mapping of the coal beds was done by myself.
The map (including sections and all, 2| feet by 1) is on a scale of -g-oVo* f ^attire, and shows the shape of the ground by contour lines ten feet apart in level. At start- ing, their height above the sea was determined by aneroid readings. The o...utcrop of each of the two workable coal beds is laid down on the map, as well as the course that a drift would take if driven level into the hill from the lowest point on the outcrop. Of the upper (3J foot) bed Jl similar level lines are drawn for every hundred feet of level from the outcrop down to 500 feet below the lowest natural drainage level. The details of the map and of the survey are much the same as those already described for the maps of the Yamukushinai, the Washiuoki and the Idzumisawa Oil Lauds already in print and need not be repeated here.
