 lockers. The desks are of 

 ash, the tops blackened, and 

 the sides treated with a pre- 

 paration of wax. Ash was used in all the furniture to match the interior

 ported against the end of the next desk, as shown in the photographs. A half

 this way any desired number of units can be combined. The last desk in the 

 row is supported by a special end.
