Mr. S. H. Conklin writes from Mt. Carmel, Conn.: "Enclosed please find check for your bilis of May 2d and i2th. I repeat the gratification I expressed before as to the convenience, the economy, and the real artistic beauty the National Lead Company's Pure White Lead Tinting colors have proved to me in using them. ít would seem as if the oíd way of trying to produce the desired shade of color by mixing many colors together with much labor and guess-work must be abandoned in favor of your economical, sure and easy method. My painters wish to introduce their use in an adjoining town, and want a couple of your books as guides."
