1 88 Book of Engineering 



The boxes which have to go abroad are 

 further strengthened by having small bars 

 nailed across them, this work is also accom- 

 plished by clever automatic machinery. 



The boxes are now ready for their con- 

 tents, and directly these have been packed 

 safely inside there is another machine wait- 

 ing to nail on the lids. This is largely a 

 replica of the machine which did the work 

 of nailing on the bottoms. 



Everything seems to go so smoothly that, 

 as with many other details in life, we are 

 apt to take the whole business for granted; 

 but it is well to give a thought to the clever 

 brains which visualised each of these opera- 

 tions and then perfected the machinery to 

 carry them out.
