Letter to James Cossar Ewart from Thomas M. Martin, 16 January 1903

 Item
Identifier: Coll-14/9/9/4
Scope and Contents

Martin advises Ewart that his notion of keeping a farm at Crosswoodburn is impractical for financial reasons. He says he is glad that 'the two hybrids' have gone to Mountain Batteries as he hopes it may lead to them being bred in India. He also mentions that Ewart 'should get a big price for 'Romulus' (Ewart's first zebra hybrid) now as he is a hybrid with a past'. He encourages Ewart to publicise his findings from his hare-rabbit cross-breeding.
