[375] Nothing was accomplished, beyond the preparation of a comprehensive report, under the chairmanship of J. W. Midgley in June, 1890.

[379] P. 12, _supra_. [380] Well brought out in the Danville case, 8 I.C.C. Rep., 409 and 571; and in the complaint of Wilmington, 9 _Idem_, 48. [381] Notable recent instances are afforded in the State Rate cases now pending before the U. S. Supreme Court, and in the Shreveport case, 23 I.C.C. Rep., 31; both discussed in chapter XX. [382] 16 I.C.C. Rep., 254. [383] Some are described in the Reports of the U. S. Industrial Commission, 1900; and the Senate (Elkins) Committee, 1905. [384] 14 I.C.C. Rep., 294. [385] "In the Southern Classification plate glass, all sizes, in carloads, is rated third class; window glass and rough or ribbed glass, fifth class. In the Western Classification plate glass, outside measurement not exceeding 100 united inches (that is, length and width added), is rated fourth class in carloads; window glass, and rough, rolled, or ribbed glass, fifth class. In the Official Classification plate glass, outside measurement not exceeding 80 united inches, is rated fourth class in carloads; window glass and rough and ribbed glass, fifth class. Thus it appears that in Southern Classification territory plate glass of ordinary size is rated higher than in Official or Western Classification territories; and while in the two latter territories plate glass is rated one class higher than window glass, or rough or ribbed glass, in Southern Classification territory, plate glass is rated two classes higher than rough, ribbed, or window glass. As applied to the transportation from St. Louis territory to Memphis it results in payment by the consignee at Memphis of rates on plate glass which are 50 per cent. higher than the rates on window glass."--21 I.C.C.
