The following illustrations come from a grade 5 grammar book called Using Our Language by T.I.Davis,
published by J.M.Dent & Sons (Canada) Limited, 1947.
I couldn't find any information in this volume pointing to whether the artist was Davis or someone else.
In the forward to Using Our Language 8 (1942), a Mr. Lloyd Scott is thanked for 'his effective illustrations'.
I believe Lloyd Scott did the drawings for both books.
