drawing, industrial mathematics, steam engineering, and jig and tool making. At the Charlestown branch are given mechanical industrial drawing and ship drafting. In the East Boston branch are given elementary and advanced machine drawing, architectural drawing, ship and yacht design, and drawing for pattern and sheet metal workers. In the Roxbury school are given mechanical and freehand industrial drawing. In the Boston Latin school building are given freehand industrial drawing and industrial design. The instruction in industrial design includes designs for book covers, plates, lettering, metal, silver and jewelry work, embroidery, costumes, decoration, leaded glass, wall paper and furniture.

The courses in industrial drawing in general cover a period of three years, except the one in drawing applied to building construction, and which is suitable for carpenters, masons and cabinet makers, which requires two years.

From the pupils of the drawing classes are formed the classes in shop mathematics; this latter subject is as yet voluntary, and has not attracted as many pupils as its importance would justify. The enrollment is largely made up of men at work in various trades, who desire to get a general knowledge of blue-prints, plans, etc.; also, a considerable number are aiming to become draftsmen.

Statistics regarding enrollment for the various classes are given in a table on page 71.

Brockton Evening Industrial School.

At a meeting held in September, 1908, the school committee of Brockton passed a vote requesting the commission to establish an evening industrial school in Brockton.

After due consideration by the commission, it was voted to establish evening industrial schools in the city of Brockton, as provided in chapter 505 of the Acts of 1906. It was also voted that the school committee of Brockton be appointed agents of the commission for the conduct and maintenance of said. schools.

The Brockton evening industrial school opened Oct. 26, 1908. Instruction is to be given on sixty nights, the schools being in

session four nights each week, Monday, Tuesday, Thursday and Friday, from 7.15 to 9.15.

The courses in the Brockton evening industrial schools are: industrial drawing (including architectural and mechanical), steam engineering, sewing, dressmaking and millinery. These courses are planned for Brockton residents who work during the day in industrial establishments.

In the high school building are held the classes in industrial drawing, freehand industrial drawing, and boiler and engine room work.

In the architectural and mechanical industrial drawing class the pupils are all men engaged in the trades, and past the age of youth. The majority of them are trying to obtain aid for their present work, and the course is made sufficiently flexible to enable each pupil to obtain instruction in his own special line. Instruction is given two nights a week.

The instruction in boiler and engine room work, including also heating and ventilation, consists chiefly of lectures, which are given once a week.

Evening instruction is given in dressmaking, millinery and plain sewing, in the Huntington, Sprague and Winthrop school buildings. In the Sprague school there are two classes in elementary dressmaking, one class in advanced dressmaking and one class in plain sewing, and there is also a class in embroidery. Each class has two periods of instruction a week. The pupils are largely housekeepers and girls who work in the shops.

In the Winthrop school building classes are held in elementary and advanced dressmaking, millinery and plain sewing. Each class has two periods of instruction per week. The pupils mostly foreigners -are housekeepers and girls from the shops.

In the Huntington school building classes are held in plain sewing, elementary and advanced dressmaking and millinery. Each class has two periods of instruction per week. As in the case of the Winthrop school, the pupils are mostly foreigners, many of whom have difficulty in understanding English.

Statistics regarding the enrollment of the various classes are given in a table on page 71.

Cambridge Evening Industrial School.

The initiative for the establishment of an evening industrial school in Cambridge was taken at the beginning of the year 1907. After some consideration of the subject, in May the school board ordered the committee on evening schools to inquire into the advisability of conducting certain industrial courses, with the co-operation of this commission.

In October, 1907, the school committee, by vote, requested the commission to establish an evening industrial school in Cambridge. The commission voted to establish industrial courses, as requested, for machinists, pattern makers and forgers; also, courses in drawing, including mechanical, architectural and freehand; domestic science; dressmaking and millinery.

The Cambridge evening industrial school was established in October, 1907. Instruction is given on Monday, Wednesday and Friday evenings, from 7.30 to 9.30, on sixty-five nights, during a period of twenty-two weeks.

The instruction in the mechanical trades, both theoretical and practical, is given in the building occupied in the daytime by the Rindge Manual Training School. The courses in millinery and dressmaking are given in the Putnam school, Roberts school, Shepard school and Webster school.

PROGRAMS OF STUDY.

Machine Shop Practice.

The shop practice in metal work consists of lathe work and construction. The plan has been formed to add work in blue-print reading to the machine shop course, in order that all those taking the more practical courses may have some exercise in the reading of drawings.

Lathe Work. Centering, squaring, turning (straight and taper); measuring by spring calipers (inside and outside) and micrometers; taper fit (lathe center); shrink fit with hole drilled (chuck drill), bored (lathe tool), reamed (hand reamer), and plug turned; eccentric centering and turning; thread cutting (R. H. and L. H., both V and square).

Construction. Steel fillister head cap screws 5% inch -11 by 2 inches, involute gears (milling machine); face plate with threaded man

drel, boring bars, etc., with work on disc grinder (shaper and drill press); double-spindle emery grinder (planer, milling machine and drill press); friction drive drill press.

Shop Mathematics.

The shop mathematics is divided into three sections: elementary, which takes up the first four rules of arithmetic and the simple reading of drawings; intermediate, which takes up fractions and advanced arithmetic, weights and measures, and the reading of more complex drawings; advanced, which takes up simple algebra and right-angle triangles, and the making and reading of drawings and third-angle projections.

Pattern Shop.

The pattern shop work takes up the explanation and use of tools, various forms of patterns and patterns for special forms of machines and machinery small rectangle, small tee iron, simple turned pattern, one piece; split pattern and core box, balanced core; flange coupling, standard core prints, with half-core box, pasted core; built-up work, small patterns; built-up segment work, pulleys, etc.; patterns for drill press, with core boxes; patterns for emery grinder, base (lagged) and hood, with core boxes, table and rest; also hangers and pulleys for counter-shaft; lagged patterns for two-wheel emery grinder, core boxes, etc. (weight of base, 480 pounds); lagged patterns for disc grinder; patterns for revolving swage block for forge shop, also carriage for same; patterns for lathe chuck; patterns for 16-inch split pulleys; patterns for angle irons, drill vises, jigs and fixtures to carry on work on above machines in machine shop.
