in order to do it thoroughly well ; you must work with 

 your head as well as with your hands. The gardener 

 to be a good gardener, must be able not only to dig 

 and root out weeds, but must understand something 

 of the habits and growth of flowers, fruits, and vege- 

 tables ; the farmer must know about the different 

 qualities of land, and how to cultivate the soil ac- 

 cording to its nature. Or, if a man is an engineer, he 

 must learn by close study the nature of the materials, 

 and the power of the forces with which he has to 

 deal, such as the strength of iron and steel, and the 

 true reason of why this or that is to be done. 



This was how Huber made his great discoveries. 

 He took the greatest trouble to understand even the 

 most trifling things ; nothing was overlooked. And 

 it is the same with the study of every department of 

 natural history. Observe everything. This is the foun- 

 dation of success. A well-known naturalist has said, 

 ' It is impossible to say at the moment of what use the 

 most trifling facts may be. It is impossible to deter- 

 mine the exact importance of any circumstance in the 

 history of an animal until we know its whole history.' 

 And this is most true of bee-keeping. We shall 

 succeed all the better by taking trouble to under- 

 stand the bee, and by close observation of little things 

 in its natural history. 



In order to impress this truth, and to illustrate 

 how great results may come from the exercise of such 

 a habit, a few examples may be given from the lives 

 of distinguished men. 



It is said* that ' when Franklin made his discovery
