Its purpose is to give the general textile student an intelli-gent idea of how these processes are conducted, and the principleson which they are based. The chemical and physical properties ofthe fibres are studied with a view to their behavior under the dif-ferent processes of manufacture. The application of the differentclasses of dyes is taken up, with methods of testing their fastnessand suitability for special purposes. The student also has the oppor-tunity of doing practical work in the dye house under careful super-vision, and to become acquainted with the modern methods andmachinery of DRY FINISHING In this room the second and third year students aid in finishing the variousfabrics produced. FINISHING This highly important step in the production of a marketabletextile fabric constitutes a subject which is remarkable for itscomplexity. The immense variety of goods whose points are dependent wholly upon the character of the finish whichhas been put upon them calls for the use of numerous finishingmaterials, and the application of these in their turn necessitates manydifferent machines. The subject is treated in its broader sense bymeans of lectures throughout the season. The general under-lying principles of the art arc, however, exemplified by the actualfinishing of many of the fabrics produced in the school, andthe students have the opportunity of assisting in the incidental ., SS REGULAR COURSE—THIRD YEAR operations, as well as in the mixing of the necessary following gives a general outline of t
