Another most important use to wbich it has been applie<l, is insula- 

 ting telegraph wires, which it accomplishes in the most perfect man- 

 ner, being sufficiently flexible for any purpose connected therewith, 

 and it is also a perfect non-conductor. By the appUcation of this as 

 an insulator, the telegraph lines now find no difficulty in crossing our 

 widest rivers and bays, where before they were cut off. The line 

 under the Hudson river crosses at Bull's ferry, and consists of two 

 wires of one mile in length each, with about 3000 pounds of cast iron 

 anchors to keep them in place. There is no doubt that the unsightly 

 poles with strings and kites flying at every few feet distance, which 

 now disfigure the principal thoroughfares of our cities, will soon be 

 superceded by isolated wires placed under the surface. This will 

 be found the most perfect mode of construction, and in all probability 

 the cheapest for cities. 



Gutta Percha has been very extensively used for machine banding, 

 both in England and the United States, and from the multitude of 

 testimonials in its favor for this purpose, the conclusion is irresistable 

 that it answers fully the required end, except in positions where ther« 

 is necessarily much friction. 



For the soles of boots and shoes it answers an excellent purpose. 

 It is more durable than leather, and can be rapidly appUed by any 

 person ; therefore in new countries, or in places where there are no 

 boot or shoe makers, it is a very desirable article. 



We have seen a great variety of house-keeping utensils beautifully 

 desigried and made of Gutta Percha. These in a great measure will 

 take the place of articles made of porcelain, and must effect a very 

 great saving, particularly in our large hotels. 



We understand that the French and English governments have 

 contracted for a sea line of telegraphs across the English channel from 

 Dover to Boulogne, which is to be completed the present year. This 

 can only be accomplished through the agency of wires insulated with 

 Gntta Percha.
