In this latter capacity he had activeresponsible charge of the engineering depart-ment, and general responsible oversight otthe draughting and testing departments. Hisduties in the engineering department includ-ed the perfecting and standardizing of thestock forms of dynamos, motors, and otherapparatus, and the designing of all odd ma-chines for special purposes; also the prepa- cell,—remarkable for its extreme sensitive-ness, reliability, and ease of manipulation;permitting the transmission of messages atthe highest speed attainable by a telegraphoperator, with a very small expenditure ofenergy.

Mr. Vreeland held this position with theCrocker-Wheeler Co. until 1900, when he re-signed to join an exploring expedition in theRocky Mountains. While in the West hecontinued his earlier work in electricaltheory, with especial reference to its applica-tion to wireless telegraphy. An article on Maxwells Theory and Wireless Telegra-phy was published in the Electrical Worldand Engineer, September 13, 1902, and hehas since issued a book with the same the products of his work in this lineis a new type of detector for electric waves,—a highly specialized form of electrolytic jointly with Messrs.
