Found - this small keepsake card with deckled edges published by Mowbray's (bookshop chain and publisher.) It was written by Margaret Smith-Masters, a poet, novelist and translator (from French) who seems to have flourished in the early part of the 20th century. COPAC record a dozen works by her between 1907 and 1936, including one on boy scouts and one published by Burns & Oates, which might indicate she was Roman Catholic. This piece in fake 'Olde Englishe' is reminiscent of the more famous Patience Strong or Wilhelmina Stitch...
against Ache of the Herte
A lyttel Silence
And of Charitie much quantitie
And of Courtesie a good lie store:
Add thereto some portion of the lowly
Of balme of Kindnesse be prodigale;
Season these with spice of Wisdome
And temper with dewes of Mercie;
Of oile of Gladnesse droppe full measure,
And blende alle with sweet Patience.
Be spende-thrifte of this salve for comfort
of thy fellows
As through the world thou wendest;
Soe shall Ease of Herte be ever thine.
Margaret Smith- Masters
