subsequently enlarged and improved, and glass-making became 

 one of the recognized industries of Pittsburg. A glass-house 

 has ever since been in continuous operation upon the very site 

 of this early factory. It can not be said, however, that glass- 

 making was really an assured success in Pittsburg until as late 

 as 1830. 



The other colonies were also more or less active in glass pro- 

 duction. Attracted by the cheapness of fuel and labor, Mr. 

 Robert Hewes, of Boston, set up a glass-house at Temple, 1ST. H., 

 in 1780. Like most industrial pioneers, he had rather a hard 

 time of it, and, after making some window glass and hollow 

 ware, abandoned the enterprise in the following year. , A refer- 

 ence in Washington's diary shows that glass was made in New 

 Haven, Conn., in 1789, and a glass-house is known to have been 

 in operation at about the same time in Hartford. In Maryland 

 the industry obtained quite a firm footing. The Legislature en- 

 couraged it by loans, and the General Government in 1789, at the 

 instance of Mr. Carroll, gave American glass works the protection 

 of a ten-per-cent customs duty. The first factory was located at 

 Tuscarora Creek, near Frederickstown, and was known as the 

 Etna Glass Works. Like so many other glass factories, it was 

 under German management, the owner being Mr. John F. Ame- 

 lung. The works were started in 1775 and were moved to Balti- 

 more in 1788. Both sheet glass and bottles were produced, the 

 output enjoying a high reputation for superior quality. But, in 

 spite of its technical success, the venture was a financial failure, 

 and had finally to be abandoned. The " Baltimore Glass Works," 

 established in 1790, were more successful, and, I believe, are still 

 in operation.

By the death of Lord Tennyson, says Nature, " not only does England lose 

 one of her noblest sons, but the world loses the poet who, above all others who 

 have ever lived, combined the love and knowledge of Nature with the unceasing 

 study of the causes of things and of Nature's laws. "When from this point of view 

 we compare him with his forerunners, Dante is the only one it is needful to name ; 

 but although Dante's knowledge was abreast of his time, he lacked the fullness of 

 Tennyson, for the reason that in his day science was restricted within narrow 

 limits. It is right and fitting that the highest poetry should be associated with 

 the highest knowledge, and in the study of science, as Tennyson has shown us, 

 we have one of the necessary bases of the fullest poetry— a poetry which appeals 

 at the same time to the deepest emotions and the highest and broadest intellects 

 of mankind. Tennyson, in short, has shown that science and poetry, so far from 

 being antagonistic, must forever advance from side to side." Tennyson was a 

 Fellow of the Eoyal Society, and that body was represented at his funeral by its 

 president and officers. Prof. Lockyer speaks very highly of Tennyson's interest 

 in astronomy and acquaintance with it.
