accompanying the Index of the Stratigraphy of North America, 16 only upper Cretaceous and earlier Tertiary are shown, with the exception of a coastal strip of Quaternary, in this part of the Island of Cuba. In the text of this paper (page 643) T. W. Vaughan says: "Strata have been referred to this age (Upper Cretaceous) in the literature on Oriente Province, but as no fossils have been listed there is doubt as to the extent of the area underlain by the Cretaceous in this portion of the island." No credence, therefore, is placed in Wedding's reference of the limestone to the upper Jurassic. Kemp, and Lindgren and Ross express no opinion on the subject, but Kemp says "fossils would be of extreme interest." In view of this uncertainty in regard to the age of the limestone, and the interest attaching to its determination on account of its close association with the iron ores, we were quite surprised and highly pleased to find fossils at a small mine known as Barcelona No. 2, which lies a short distance west of the Lola Hill mines. The fossils, which include corals and sponges, were submitted to Dr. T. W. Vaughan, who kindly gave us the following information in regard to them and the age of the rock. The corals belong to the genus Leptophyllia (?), a species of which is found in the Cretaceous of Jamaica. Doctor Vaughan says no similar coral is known in any of the Tertiary of the United States or the West Indies. The sponges are also Mesozoic and probably Cretaceous. The age of the limestone therefore is definitely fixed as Mesozoic and probably Cretaceous. These fossils are of importance as being apparently the first Mesozoic fossils found in this part of the Island, and more particularly as furnishing the first definite information in regard to the age of the limestone associated with the Firmeza and Daiquiri deposits. It was late in the afternoon when we visited this mine and there was little time for collecting. A more careful search than was possible in the limited time at our disposal would undoubtedly reveal other forms, as well as other localities at which the limestone is fossiliferous, and ultimately make possible a still closer correlation. 16 Bailey Willis: Index to the Stratigraphy of North America.

Absolutely-or mines, cement plants, sand and gravel plants, sugar refineries and other users demanding service and low cost, would not buy 17,118 feet of this brand in one month. Add in other brands and the Goodrich Conveyor Belt output totals 26,525 feet for 30 days. We do not claim a low first cost-we cannot without forfeiting quality. We do claim that your plant costs chargeable to the belting account will be low, regardless of first cost. We furthermore claim that Goodrich Conveyor Belts symbolize the highest degree of quality and workmanship for straight running, troughing without load, edges that won't peel or break loose, minimum stretch and, therefore, greater "Tonnage." These claims are based on what users of this monthly output of 26,525 feet say - and the cost sheets they are able to show us. Would you like suggested specifications for your conveyors? Describe them and we will show you belts that make good in the hardest kind of service. The B. F.

MANUSCRIPTS FOR THE ARIZONA MEETING OF THE The next meeting of the Institute, the 113th meeting, will be held in Arizona in the latter part of September, 1916. All papers to be presented at this meeting must be published in the September Bulletin or previously. Manuscripts must, therefore, be in the hands of the Secretary of the Institute not later than July 1. In case manuscripts are given by authors to members of technical committees, or others, they must be in the hands of such persons sufficiently in advance so that they may be actually in the hands of the Secretary of the Institute by the date mentioned. In the past, the Secretary has received urgent requests for special consideration regarding manuscripts that come in after the closing date. In view of the obvious unfairness of this, the Committee on Papers and Publications has instructed the Secretary not to accept for presentation at the Arizona Meeting any papers received later than July 1, 1916. iii |
