 of the process is performed in its particular manner.

 grafting, but he cannot graft intelligently. The arti- 

 san, however skillkul, who knows only the art, cannot

 learns also the science that underlies his trade. 



The art of doing any kind of work is best learned by

 affected by various external conditions, as heat, moist- 

 ure, light, food, etc. These conditions and all others that 

 influence the plant or animal make up its environment. 



4. What is Culture ' The well-being of a plant or 

 animal depends very much upon a favorable condition 

 of environment, and with the proper knowledge, we can 

 do much toward keeping the environment in a favor- 

 able condition. For example, if the soil in which a 

 plant is rooted lacks plant food, we can enrich it; if it 

 lacks sufficient moisture, we can dampen it ; if the plant 

 is shaded by weeds, we can remove them. These, and 

 any other things that we can do to make the environ- 

 ment more favorable, constitute culture in the broadest
