Letter to James Cossar Ewart from Sir Claud Alexander, 06 June 1914
Alexander reports that his pregnant mare has died. He asks whether Ewart would like to take on all of his fat-rumped ewes for £10. He has a donkey very near foaling by the mule 'Jacob', which proves that he can still get stock. He states that can give Ewart the breeding of the sheep if he saw them.
Letter to James Cossar Ewart from Walter Heape, 18 January 1899
Heape offers advice on how to compose a scheme of recording the following data from experiments: details and date of service of mare, date of birth of the foal, in conjunction with the number of times the mare was served. This information might indicate any retardation of ovulation, or any hindrance to the passage of sperm into the uterus.
Letter to James Cossar Ewart from Wilfrid Scawen Blunt, 22 July 1896
Blunt invites Ewart to a sale of mares at his horse farm near Horsham, Sussex. Blunt writes that the mares are likely to be in foal and would probably fetch 50 or 60 guineas.
Letter to James Cossar Ewart from William Allison, 16 February 1899
Allison agrees with Ewart about the importance of nutrition in a horse's pregnancy, and supplies information relating to two mares from Ireland. He makes an observation regarding British thoroughbred horses and their lack of robustness due to their breeding habits, comments on various Australian thoroughbreds and reveals his experiences of fox terrier breeding.
Letter to James Cossar Ewart from William Bernhard Tegetmeier, 25 August 1896
Tegetmeier writes concerning mule mares. He also reports some 'gossip' about Dr Butler of the British Museum and his assertion in The Feathered World that he had seen two mules in foal in a drove of 50 in Spain, and the driver had told him mule mares were often infertile. Tegetmeier remarks 'That a man in his position should publish such nonsense is very unsatisfactory'.
Letter to James Cossar Ewart from William Gordon, 01 October 1917
Gordon writes that unfortunately nobody in the district is selling a Shetland heifer in calf, but that he would be willing to put an advertisement in the Shetland News for Ewart. He reports that he doesn't have any crosses between Blackface tups and Moorit ewes, but that he will set aside any long-woolled Moorits he comes across for Ewart. He also offers to send him a white pure Shetland tup lamb with three horns.
