Elwes suggests that he and Ewart write a joint paper on sheep. He proposes to visit and photograph each different variety of sheep if they are not mongrels. He has heard of a flock of Faroe sheep near Peterborough as well as sheep in Brittany and Iceland.

Elwes writes that he is glad that Ewart does not object to joint work, and suggests starting the study with 'the Highland Society' before doing something more ambitious in a few years' time. He asks Ewart to seek out the papers of a society formed more than a 100 years earlier in Edinburgh for the improvement of sheep and wool.

The year is not written on the letter.

Hayes thanks Ewart for an enjoyable visit to Penicuik. He would like to publish a book on horse breeding and would like to discuss the details with Ewart, with a view to collaborating with him.

Hayes states that he hopes Ewart received the pulls of blocks he had produced from the negatives of the Norwegian pony and the long-maned pony, bay and foal. He has also recently received some photographs of typical Australian and Chinese ponies. He is pleased that Ewart thinks favourably of the idea of the two of them collaborating on the writing of a book on horse breeding and proposes to first publish a few articles in the Live Stock Journal.
