themselves.'-..-When 'we. consider tins we mav well C3i3c to wonder at the gullied hills, egregious blun ders, and numerous faihrcs which mark the ca reers of 'many farmers of Virginia. The captain of a rrian-of war docs no work with'his hands, he neither trims the sails, nor holds the helm, nor heaves the lead. Has ho therefore no work to do? Is he a drone ? Coufd the ship sail as well with out him ? Far from .it 5 he is the very soul of ev ery operation on board. Sovould it be with ev ery Southern .farmer. His ofEce is to Jcnotc all that can be known about fanning, (as the captain does about navigation) and to direct, superintend and control, the execution of the farm work by them whose business is bodily labor. But it is stf much caaicr to work with the hands than to do all this, and men are so prone to seek their case, that the farmer too often surrenders his high office for a much iguoblcr one. The same indolent spirit would make tho captain of a ship exchange places with his boatswain. What a sir :v : hould wish to shun a high and v. ; which affords ample acope and vc'r - " for the loftiest and brightest int' " ! When will our young farmers learn to ? ihar true work, and endure the mental toil z:ry to win the glory of it ? Yet must they ,. ), too how tc do all the bodily work of the farm, l that not theoretically only, but practically j and the better they so know it, the better farmers they will be. Not because they shall do the work hither with them ho more thinking mind than the .'stalled ox ? Seeing do they see not, neither un derstand ? Surely, surely not. We come hither to get knowledge and ; to communicate it. The prime benefit of these gatherings is that they set us to thinking. Hence we get wisdom by hearing and seeing, because and in proportion as we have the power to think. Men learn to think by obser vation, experience and education j and by inter course with other men the latent sparks of thought are kindled, just as the Ore of tho flint is stricken out by the steel. Agricultural progress advances with new aud rapid strides as men acquire new powers of thought from observation and experience. When our Fairs cease to afford them they will have become efTete and worthless, and will do no good to any but premium huutcrs. When their value becomes to be estimated in dollars aud cents, they had a3 well be abandoned. I have said that the power to think may be ac quired by proper educational training. I am quits sure it may. But it is much to be regretted that many of us begin our profession with such imper fect preparation for the duties of it, that even af ter a life-time spent in the work, we have hardly acquired the faculties of decuction and generaliz ation which are necessary for the discovery of truth. Hence some in despair of establishing the science of agriculture on the firm basis of exper imental truth, have abandoned the work, crying out with the Preacher, "vanity of vanities, all is themselves, but that they may know how to have vanity." But not so. Truth, indeed, comcsslow- it done, and when it is done properly. Neither! ly, but she comes surely to them who seek her mint they withhold their hands from any kind of j right. .Men gn.cl at tho starry tirmameut mora work, if duty calls them to engage in it. But their daily work, their "appointed work which declares their dignity," is of the mind. Some men . speak lightly of head work as being easy. But I do not know any kind of work which wo are more prone to shun, or which men do less of, or do worse. Of all my acquaintances among my brother farmers not one in tour thinks closely, carefully and systematically about his business. The pther three are copyists, or tread the beaten track of their forefathers flaring up occasionally in fitful efforts of sickly and unfruitful thought. Thinking is the hardest work meu have to do, and hence we have so few real thinkers. Will any say Farmers have no need to think Then why have agricultural journals? Why have this soci ety? Why these yearly avalanches of the people on this most hospitable city ? Do men come here merely to glut their eyes with sight-seeing, and Orgc their inawiwith feasting?. Do they bring than five thousand vears before the red streaked apple, which fell at Newton's feet, suggested to his mind the law of gravitation, and revealed the mysteries ot astronomy. .Newton s mum was weu stored with learning. Kducation had trained him to think, else had that red streaked apple fallen in vain as unnumbered ones had fallen before by ev ery autumnal wind. If we would watch the truthi of agricultural science, we must train the farmer how to hunt fur them. This brings me to the consideration of another moral obstacle in the way of agricultural progress which is the want of scientific knowledge. By " scientific knowledge," I mean all that knowledge of farming operations which a man may acquire, either from books or from other men, independent of his own practical observation or experience. This may be a broad definition oi agricultural science, but I think it, nevertheless, the true one. I The science of any profession is what men have
