Cropper was an active director of the Liverpool and Manchester Railway from 1830. In 1833 he decided to start an industrial school for boys, in the area of agriculture; and after visiting Germany and Switzerland, he built a school and orphan-house on his estate at Fearnhead, near Warrington, with a house for himself. Here he resided until his death, in 1841. He died in 1841, and was buried in the Quaker burial-ground at Liverpool by the side of his wife. The house at Fearnhead bore the following inscription:
"In this house lived James Cropper, one, and he not the least, of that small but noble band of christian men who, after years of labour and through much opposition, accomplished the abolition of West Indian slavery; and thus having lived the life of the righteous, he died in the full assurance of faith on the 26th of Feby. 1840."
