These looms, with, the aid of the Jacquard attachment, have en- 

 larged the field of art in woolen fabrics, so that it now presents a 

 limitless opportunity for the play of genius. In this direction we 

 may look for constant advances. In recognition of the oppor- 

 tunity, textile schools for the better education of tliose who have 

 to do practically with the manufacture have been established in 

 the chief manufacturing nations of the Continent and in England. 

 The influence of these schools upon the character of woolen fabrics 

 is increasingly perceptible and is most gratifying. It is this in- 

 fluence which to-day constitutes the chief advantage which foreign 

 manufacturers possess over those of the United States in the 

 woolen manufacture. Nor can we hope to equal their achieve- 

 ments in this country until we have supplied the means for the 

 better technical education of those who determine the character 

 of the fabrics made in the American mills. In machinery equip- 

 ment, and in all appliances for economical production, our best 

 mills are fully abreast of the best foreign mills. But in the 

 character of our products we continue to be imitators rather 

 than originators. 



MAN AND THE GLACIAL PERIOD.* 



By Pkof. G. FREDERICK WRIGHT. 



Qi OME most important facts have come to light during the past 

 ^-} two years bearing upon the connection of man with the Ice 

 age in North America. 



In October, 1889, Mr. W. C. Mills, president of a local archaeo- 

 logical society of some importance at Newcomerstown, on the 

 Tuscarawas River, in Ohio (see map), found a flint implement of 

 palaeolithic type fifteen feet below the surface of the glacial ter- 

 race bordering the valley at that place. The facts were noted by 

 Mr. Mills in his memorandum-book at the time, and the imple- 

 ment was placed with others in his collection. But, as he was not 

 familiar with implements of that type, and did not at the time 

 know the significance of these gravel deposits, nothing was said 

 about it until meeting me the following" spring, when I was led 

 from his account to suspect the importance of the discovery. Mi-. 

 Mills soon after sent the implement to me for examination, and 

 its value at once became apparent. In couqmny with Judge C. C. 

 Baldwin and two or three other prominent citizens of Cleveland, 

 I immediately visited Newcomerstown. A cut of the implement 

 is given in the accompanying pages, made from a photograph one
