appears to answer the purpose ? I strongly advise all 

 who gain their living by tilling the soil, as well as the 

 agricultural student, to take nothing for granted ; but, 

 should the meaning of what he is doing or reading not be 

 apparent, not to rest until it is clear to him as the sun 

 at noon day. This course will not only make the work, 

 whether manual or mental, much more easy ; but the 

 enquiring mind will often find rays of light at unexpected 

 times, and in unlooked for places, which will dissipate as 

 fallacies, old received practices or opinions. Our marvel 

 at the Italian peasant, with his traditionary blunders, 

 ceases when we observe the wonderful manner in whicli 

 writers, many of them authorities, will copy from each 

 other and perpetuate errors ; and it is only upon labori- 

 ous comparison of the dicta of various authors that the 

 student will discover the prudence, while accepting their 

 general guidance, of testing everything he learns by 

 his own reason, or by experiment.
