Cooking in difficult times

My mother has a copy of Mrs Arthur Webb's 'War Time Cookery - published 1939 (reprinted 1940), she clearly didn't hang about. There's this to give the flavour:
Casserole of cucumber -

• 4 small cucumbers
• 1/2 lb of sausagemeat
• 3/4 pt of stock
• 1 turnip
• 3 carrots
• 6 small onions
• seasoning

I don't have the precise method here but she does recommend removing the cucumber seeds before cooking.
