30 TRANSPORTATION OF THE EGGS.

 adopted, namely: 



Discard the pebbles altogether, and take clean, 

 fine, wet sand, in boxes devoid of holes. Spread 

 the sand on the bottom of the box; on this sand 

 place a layer of eggs, at the same time being very 

 careful not to permit the eggs to touch each 

 other; then over these eggs spread another layer 

 of sand, and then, another layer of eggs, and so 

 on alternately until the box is rilled, so that the 

 lid presses on the sand; this will prevent any 

 motion of the contents of the box. The box, 

 with the contents, but the lid removed, should 

 then be dipped in clean water, for the purpose of 

 having the sand thoroughly saturated; after this 

 has been accomplished, the lid may be fastened 

 down. 



The boxes should be kept in a low tempera- 

 ture not so low as the freezing point, however. 

 The boxes which I use are made of tin, and in 

 size are .about five inches in length, the same in 

 breadth, and about four inches deep. The boxes 

 used by M. Costa are made of wood, and are 

 somewhat larger than those above described. The 

 boxes should not be much larger than those 

 which I use, for the reason that in larger ones 

 the weight of the sand would injure, if not de- 

 stroy -the eggs,
