Originally published in 1906 as part of the National Problems series, this book explains both the scientific and practical aspects of the breeding industry in Britain. Heape stresses the importance of the animal breeder as part of the agricultural and economic infrastructure of the country, particularly at a time when horses were still used for transportation, and suggests ways in which the government of the time could be more supportive to animal breeders, who perform such a significant yet often overlooked role. This book will be of value to anyone with an interest in the history of British agriculture and animal husbandry.
