Kenya Diary - 1902 - Tate sent by Sir C. Eliot to investigate and collect evidence to enable the Government to prosecute 3 European traders who are now in custody in Nairobi, charged with murder, raiding and the wholesale slaughter of elephants. The names of the 3 are Smith, Vincent and Atkinson. ...... I understand Tate had great difficulty in persuading either Rendille or Samburu people to come to Nairobi to give evidence against Smith, Vincent and Dr. Atkinson, who had been raiding around Marsabit. These ruffians had brought a huge herd of sheep and goats to Naivasha and then to Nakuru. ...... with the greatest reluctance 3 witnesses were brought back. Donald, the Town Magistrate heard the case, and Arthur Neumann also gave evidence for the prosecution. The accused were committed to the High Court, where they were tried before a panel of settlers, but no white jury would ever find a white man guilty on coloured evidence.

White Man - "The Doctor" to all who remember EA in its pioneer days. ........... had taken up some land at Karura 5 miles outside Nairobi. He imported a Shorthorn bull as a present for Delamere and a Berkshire boar. .........

Delamere's nearest neighbours at Equator Ranch were Dr Atkinson and his brother, who worked a sawmill on the forest's edge.

Playne - The Equator Sawmills - It is 11 years since Dr. Atkinson came to BEA, in the company of Lord Delamere. Mr E.C. Atkinson came in 1900, and started the first sawmill in the country at Nairobi. Four years later the Equator Sawmills were started with Dr. Atkinson and Mr E.C. Atkinson as partners. The mills are 1.5 miles from Molo or Elburgon on the railway line, and have their own siding. .......... Six Europeans are employed on the staff. The partners own 10000 acres of land on either side of the railway, making a total of 20000 acres, mostly timber ......... Logs are taken into the mill by means of oxen, and contracts are let for haulage. ........... Messrs Atkinson had the first imported pure-bred bull in the country, and still take keen interest in stock, but owing to their sawmill business they find their time fully taken up now. They own 10000 acres at Londiani, on which a house has been built. Dr Atkinson has taken a keen interest in the Pastoralists' Association, and Mr E.C. Atkinson started the Colonists' Association.

Nicholls - The early white hunters sometimes behaved very badly towards Africans. A.E. Atkinson pitched camp in the middle of an Embu shamba and helped himself to the crops to demonstrate how powerful he was. Unsurprisingly, his loads were stolen and 2 of his porters killed. So Atkinson retaliated by shooting 12 Africans and burning a village.
