After the annealing is accomplished, the ware is put 

 into trays, each kind or different mark by itself, and is 

 taken to the packing department, where the perfect 

 ware is sorted from that which is unsaleable and is then 

 packed in boxes, branded, and is then ready for the 

 market. 



The manufacturing of the different varieties of glass 

 in the United States is carried on very extensively, and 

 the demands of our home market continue to increase 

 year by year. This may largely be accounted for by the 

 comparatively low cost at which it can be produced. 



The industry is divided into various branches, which 

 are quite separate and distinct from each other. They 

 are the manufacturing of window glass, bottles and 

 hollow ware. The window glass industry may be sub- 

 divided into the manufacture of polished plate glass ; 

 our product of this variety now comparing very favorably 

 with the foreign makes ; rough plate or ribbed glass, 

 which is largely used for roofing and flooring purposes ; 

 and common window glass, the quality of which is too 

 often sacrificed by the use of cheap materials. 



Bottle manufacturing may be subdivided into three 

 classes. Flint or white glass bottles for cutting and en- 

 graving ; flint bottles for prescription use, and or- 

 dinary green glass bottles, used for a multitude of pur- 

 poses. 



In the manufacture of hollow ware, such as lamp 

 chimneys, goblets and general table ware, we are said to 

 excel our foreign competitors. 



While we enjoy great natural advantages, such as 

 cheap fuel in the form of coal, natural gas and crude oil, 

 we are much behind our foreign competitors in the 

 matter of furnace construction. In Europe, tank fur- 

 naces have almost entirely replaced the old style pot 

 furnaces, the result being greater economy in the cost 

 of manufacturing. It is largely due to the fact that our
