    "It [Troutbeck] has religious isolation also, for it is several miles—and very strenuous miles in winter—from the parish church at Mungrisdale, and the introduction of the harmonium to the waiting room was due to the zeal of a vicar of many years ago who, in the absence of any other room in the village, obtained permission to use the premises for services, including Sunday School.
