Copies of approximately 1000 letters, averaging 1 per page. Some letters illegible due to fading. Contains many letters relating to ongoing sale of the Purdon Estate, Philipstown (Daingean) as well as letters relating to the Geashill Cattle Drive.
Includes letter to R. F. Barry, Esq., Crown Solicitor re The King v Adams and 45 others Geashill Case: 'I give you on annexed page particulars of the rail fare paid by the 45 defendants to take them to Kingsbridge for their trial in December last. There were 46 charged, but one, Thomas Hynes, was a prisoner and was conveyed up by the Authorities. Two witnesses were also brought up, namely, Father MacDonald and Dr. Barry of Philipstown, and both were examined. I also include their single fares. The accused and the witnesses had, of course, to be conveyed to Green Street, and I put £1 down for this though it would not probably nearly cover it as several of them took cars from the station. There can be no controversy however about the railway fares. I also give the figure of the return fares in case these are allowed. The parties had to come back, and as a matter of fact, were kept in Dublin two days; but I do not think these expenses are payable. I trust you will be able to kindly have whatever they are legally entitled to paid to them through me.' (29 March 1915)
