Karapuka Training Camp - location, meaning, and purpose unknown

This was probably in the environs of Calcutta but I have had no luck finding details. They had a dormitory and boys of all ages in residence.

Maybe it was some kind of rural boarding school. If anyone knows, please contact me. See the 'contact' tab above.
