The school possesses a well-equipped practical dye-house and each student has to work out various problems in dyeing on a comparatively large scale. Upwards of five hundred different lots of wool, cotton, silk, mercerized cotton, etc., in the form of yarn, loose stock, and cloth, and varying from one-half pound to forty pounds in each lot, are dyed in all manner of different shades for different purposes. To match selected colors, the student is given excellent practice. We believe a larger amount of practieal work is carried out in the dye-house of the Philadelphia Textile School than in any similar institution eitner in this country or in Europe.
