The Eureka Silk Manufacturing Company
http://bit.ly/ArnoldCollectionsAppendix1Eureka

The Eureka Silk Mill originated in Canton MA, whose Historical Society maintains what they claim is the "biggest local history site in America." 

After its founding, the Eureka Silk Manufacturing Company expanded and changed hands. The history of the Company is convoluted, as it appears both several different locations as well as owners were involved over the life of the company.

One of the owners was H.K.H. Silk Company (scroll down), which had a connection to M. Heminway & Sons Silk Co., publishers of this informative pamphlet on silk manufacture. At least we'll know something about silk, if not the company itself!

The reverse of a few of the Eureka cards reveals the variety of thread types available from Eureka:

It appears that once the business left Canton MA, it had a presence (whether it was manufacturing or sales is not clear) in NYC, Boston and Chicago as well as various locations in Connecticut. Here are some traces of those locations as found on printed mailing envelopes and Google Street View:
