51 Jan 15 I write - some sort of potentiometer approach. I then had tea and cakes with the principal & Dr. Ngiam, wrote a comment in the guest book - mine the first entry in a new book, then we went out to the school yard and watched the entire student body of 1300 boys do a series of setting up exercises in precise drill tempo. A teacher call orders from a microphone on a platform overlooking the field. The boys were well disciplined and kept a perfect rhythm of activity. When I came to the platform they clapped and the principal said it was a greeting. At the end of the drill the field was quickly cleared as the boys marched off in twos, arms swinging stiffly through a large arc. I learned that this was the biggest institution of its type in Delhi - that the labs hold 24 students and that a given lab. handles 450 students a week. A lab is open from 7:30 am. to 1 pm. The school is on split shifts to handle its large enrollment. Each lasts 35 mins. The building was mortar covered, paint weathering & steps of stone worn. It looks like it has had long use.
