Fig. I. A view of the "angle iron" frame liolding seven glass trays. Two 

 additional trays in different positions, with their glass lids leaning against them, are 

 shown. The white objects in the foreground are paraffined muslin strips, which are 

 used with the glass lids to effect air tight closure of the trays. 



Tray I in the second stall of the first tier has a glass lid in place, which shows 

 distinctly in the picture. The trays in the stalls diagonally downward to the right of 

 Tray I, and also the tray in the second stall of the lowest tier, are empty and without 

 lids. The two covered trays in the fourth and fifth stalls of the second tier contain 

 frozen hashed meat and show the usual appearance of full trays in reserve in the frame. 



Trays II and III outside the frame show clearly the inside appearance of the 

 trays. 



The removable horizontal rods are in position to prevent forward movement of the 

 trays. The special turns on the ends of the rods should be noted.
