Half-Pay Pudding

I was reading the proofs of the book last weekend.  Neither Hampshire six cup (equal volumes SR flour, breadcrumbs, dried fruit, suet, sugar and milk), nor its close relation, half-pay pudding (same, but double dried fruit and some treacle), had eggs in them. This didn't feel right. How would it stay together? As I hadn't made either for some while, I made a half-pay pudding for dinner last saturday.  It was a big one, and I was feeding ten, but there was some left at the end (but no treacle tart, and virtually no blackberry and apple tarte Tatin), which I have been muching through ever since.  You don't need eggs in Hampshire six cup or half-pay pudding!
