My great grandfather John Joseph Donnelly was the teacher at Sweet Briar and Balfour public schools in 1917.

(From a Correspondent.)
Haymaking is in full swing here. The weather during the past wekk has been ideal for getting in the crops. A considerable quantity of hay has been destroyed by the heavy rains of a little while back.
The Department of Education has closed the Sweet Briar and Balfour schools on account of small attendance, and the teacher Mr. Donnelly, has received notice of his appointment as assistant in the first-class public school at Erskinville, Sydney. Mr. Donnelly has put in five years here and he richly deserves his good fortune. The appointment means promotion in his profession and financially, and he is to be congratulated.
