While studying at the university, he became the secretary to the committee producing Life and Work, a Church periodical, and also learnt here the importance and power of propaganda and dissemination of information.
It also housed "Guild mission" and a training school for catechists; later, with growing diseases, a hospital with 25 beds was opened in 1893.

Graham and his other missionaries were also criticised by Lepcha Christian communities, who felt that they had been educated for only vocational pursuits and not for business, trade or commerce.
