'At first when African farmers saw European devoting time and labour to manuring their lands they regarded it as another instance of white man's folly. But they began to notice that the white men's fields grew more and better produce and for years the Agricultural Officers of the Government patiently explained to the Africans how the land must be fed with manure if it was to continue to yeild[sic] good crops. At last the lesson is sinking in the African begins to use his farmyard manure previously dumped at the village gate as a sign of his wealth. In 1945 one Local Council in the Kiambu district near Nairobi appointed an elderly Kikuyu as a buying agent for manure. Two buying posts were set up and native syock[sic] owners brought in their manure by head lead and donkey selling it at five cents of a shilling for as much as would fill a four gallon tin. The Local Native Council in turn brought from him at 7 cents a tin and supplied to farmers a[t] 7 cents plus transport. In this district alone about 360 tons of manure were sold during March of 1945 and over 800 tons since the scheme started to operate - evidence of the increasing awareness of the more educated African of the neeeds[sic] of their soil'.
