J. W. Robertson Scott, The foundations of Japan
“ It is because more than half the paddies are always under water that rice cultivation is so laborious. Think of the Western farm labourer being asked to plough and the allotment holder to dig almost knee-deep in mud. Although much paddy is ploughed with the aid of an ox, a cow or a pony, [73] most rice is the product of mattock or spade labour. There is no question about the severity of the labour of paddy cultivation. For a good crop it is necessary that the soil shall be stirred deeply. ”
