De Margerie, Reid, Lamplugb, and the southwest tributary of 

 Rendu glacier advanced during 1913. The great Muir glacier 

 continues to retreat. A comparison of the map of 1892 with that 

 of 1913 shows a recession between those dates of 7 '76 miles. This 

 glacier is now well displayed for measurement and it is found to 

 have been 23 7 S feet thick at a point 5M5 miles from the terminus 

 of 1892. The thickness of ice in the Grand Pacific glacier 12*1 

 miles from the terminus 1914 was at least 2493 feet.

7. Additional Facts in Regard to the Discovery of the 

 Meteorites of llrenham, Kiowa County, Kansas. — The remark- 

 able group of pallasites of Brenham, Kiowa county, Kansas, were 

 described by Dr. George F. Kunz in this Journal for October, 

 1890 (vol. xl, p. 312). Recently Mr. John W. Davis of Greens- 

 burg, Kansas, who first called attention to this occurrence, has 

 given to the editor the following facts in regard to the discovery, 

 which fix the exact date of the find : "I first saw this meteorite 

 on the 20th of September, 1885, and at once identified its meteoric 

 nature. Cowboys riding over the prairie, and cattlemen occupy- 

 ing the country between the Medicine River and the Arkansas 

 River, had known of the strange heavy stones at least four years 

 before that time. It was one of them who took me to the place 

 and showed them to me. After I identified them as meteorites, 

 people living in that immediate vicinity took an interest in them 

 and collected eight or ten large pieces and had them in their door 

 yards and gardens. One piece weighing 202 pounds was dis- 

 covered 12 miles southwest of the place I have just described 

 about a year later. Over a bushel of small fragments were found 

 lying together and very much oxidized. Some of these little 

 ones were almost round and showed no signs of broken surfaces. 

 Outside the ^02-pound specimen mentioned, the others have all 

 been found within an area three miles long and one mile wide, 

 lying a little southeasterly. Most of them were a little above 

 the surface of the ground, just showing at the grass roots, and 

 none of them have been found with their top surface more than 

 eight or ten inches deep ; these last were completely covered by 

 soil, and were discovered by plowing. There is some broken 

 country within the area described, which has never been dis- 

 turbed, and doubtless other specimens will be found there. Ben- 

 jamin McFadden, the cowboy who told me about these meteorites 

 and showed them to me, said he buried one of them several years 

 before in a badger hole, and pointed toward the locality ; he died 

 two months later of typhoid fever, and of course no one now 

 knows the exact spot. The soil where these meteorites were 

 found is a heavy loam, black or rather dark brown in color, with 

 a small proportion of sand, and was covered with a heavy coat of 

 buffalo grass ; such a surface could hardly have been penetrated 

 very far even if the force of impact had been very great."
