Notes and Comments. 179 



on Coal Supplies, embodying his views as to the probable 

 (or possible) extension of the concealed coalfield. That 

 portion of the map which was extended in a south-easterly 

 direction into the Fen country, was rather severely criticised 

 by members of the Geological Survey at the time, and a member 

 of the Royal Commission attached to it a name which, he 

 was sorry to say, still lingered in the minds of members of the 

 Commission, and was occasionally quoted — -namely, " Kendall's 

 preposterous belly.' That extension of the coalfield was, 

 he thought, considerably sustained and justified by the work 

 that Prof. Fearnsides had done.' It is a remarkable fact that, 

 of the three hypothetical boundaries of the hidden coalfield 

 suggested by Professor Kendall, this, upon the south-east, 

 which came in for the. most criticism, is the one most strongly 

 sustained by subsequent research. 



THE SUPPLY OF IRON ORE. 



At the Royal Society of Arts recently, Professor W. G. 

 Fearnsides of Sheffield, dealing with the available home supply 

 of iron ore, said that of the 29 counties working ore, Yorkshire 

 (Cleveland) got nearly 5,000,000 tons in 1915, from which 

 1,446,413 tons of pig iron were obtained. Northampton, 

 Lincoln and Cumberland were next in order, the last-mentioned 

 county turning our by far the best value. The total output 

 in pig iron for 1915 was 4,567,351 tons. Germany had increased 

 her output of pig iron from 9,000,000 tons to 19,000,000 in 

 ten years, and our own output had not increased in ratio. 

 The hematitic belt extended in England from Cleveland to 

 Banbury, but there were immense beds of a low grade ore in 

 this country which contained a good deal of phosphorus, and, 

 therefore, not so good in the furnace. Germany's great super- 

 iority in output was due to the realisation of just such quality 

 ore, and if our metallurgists were to exploit our own supply 

 to such a good purpose as steel-making, he thought it would 

 be found there was no national shortage or iron ore whatever. 



GEOLOGICAL PHOTOGRAPHS. 



Prof. W. W. Watts favours us with a copy of the Eighteenth 

 Report of the Committee on Photographs of Geological Interest, 

 presented at the Newcastle meeting of the British Association. * 

 From this we learn that ' Mr. Bingley adds still further to 

 his photographic survey of the Yorkshire coast, as well as 

 sending sets from the Yorkshire Dales, from Settle and from 

 Leeds. He also contributes a carefully selected set from the 

 Magnesian Limestone of the Durham coast. To him we owe 

 prints from Cumberland, Westmorland, Lancashire, and the 



* The seventeenth report was presented at the Sheffield meeting in 

 1910.
