A CATECHISM 1 



OF 



PRACTICAL AGRICULTURE. 



By HENEY STEPHENS, F.R.S.E. 



Author of the ' Book of the Farm. ' 



FOR those destined to aet as principals on the farm, instruction is provided by the profusion of Treatises on the 

 various branches of the subject, by Agricultural Colleges and Lectureships, and pre-eminently by their entering 



i practical pupils with men of mature experience and skill ; but for the far larger numbers destined to sub- 

 ordinate employments, no such means, and indeed no means of any kind, have been available They entered 



i their occupation entirely unprepared for it, and were destined to acquire the knowledge and skill requisite 

 wholly empirically, behind the plough or in the fleld. That through such a training multitudes have come 

 thoroughly to understand and ably to fulfil their duties, admits of no dispute ; had it been otherwise our 

 agriculture could never have been what it is. But still it is hardly questionable but that this knowledge 

 and ability might have been earlier, more easily, and more generally attained, had these workers in our fields 

 entered on their task in some degree informed, by preliminary elementary instruction, as to what was ex- 

 pected of them. 



The favourable reception given to Professor Johnston's ' Catechism of Agricultural Chemistry and 



eology,' suggested to the Publishers the propriety of a similar work on Practical Agriculture. In intrust- 



G 



And in following out the details, he has proceeded on the principle which all teachers of mixed classes know 

 to be the only safe one the assuming nothing whatever to be known beforehand of the processes described. 

 The utmost simplicity and clearness have thus, it is hoped, been secured ; and as a still further aid to full com- 

 prehension of every operation, woodcuts and diagrams have been profusely employed wherever they could 

 be of any possible service.
