THE POSITION OF THE CASK IN THE CAB. 



The data on the damage to the eggs, <Iiu> to the part of the car 

 in which the case is placed, are given in Table !>. These data are coin- 

 piled for well and poorly loaded cars, and for both straw- and wood- 

 buffed cars. In the straw-buffed cars, as the distance from the straw 

 buffing increases, there is a slight but definite increase in breakage, 

 amounting to about 1 egg per case. Although this increase is not 

 visible in the wood-buffed loads, the total breakage with this form 

 of buffing is slightly higher. Regardless of their position the rows 

 show a uniform tendency toward an increased damage along the 

 sides of the cars, becoming progressively less toward the center line. 

 The layers of cases show no consistent tendency toward increased 

 damage in any definite locality.

THE CHARACTER OF THE BUFFING AND BRACING OF THE LOAD. 



A correlation of the character of the stowing of the load at the 

 point of origin and its effect on the amount of damage to the eggs 

 apparent at destination soon convinced the investigators that a re- 

 vision of many common practices must occur before any noteworthy 

 improvement in the condition of the eggs at the market center could 

 be expected. 



The experiments here reported indicate that the load of egg cases 

 must be ;i solid unit in the car, fitting in so tightly that not an inch 

 of play is available, and its rigidity must be entirely independent of 

 braces nailed to any part of the car. How such stowing and bracing 

 can be readily and cheaply done is told on pages 5 to 9 of this re- 

 port. Of all the various factors entering into the breakage of eggs 

 during transportation, the placing of the load in the car and the 

 maintenance of its rigidity during transit are the most important.
