GERMAN-CHILE CASE. 



Another case used on journeys in which the care of the eggs is the same 

 as above described is the German-Chile case, so called by reason of having first 

 been employed by German fish culturists in shipping trout eggs from Germany 

 to the Chilean Government. It was brought to the attention of fish culturists 

 in this country by Mr. E. A. Tulian, chief of the section of fish culture of the 

 Argentine Government. In 1907 and 1908 this case, somewhat modified, was 

 used by Mr. Tulian in transporting trout and salmon eggs from the United 

 States to Argentina with better results than had been secured with any other 

 form of case. Owing to the absence of moss directly on the eggs, the German- 

 Chile case is especially adapted to the handling of rainbow trout eggs, the mem- 

 brane of which is more delicate than that of any other species of the Salmonidae. 

 From the latest observations it is undoubtedly true that the ideal form of long- 

 distance shipping case for all species, at least when accompanied by an attend- 

 ant, is the one wherein no moss or other substance is placed directly on the 



eggs. 



The German-Chile case is constructed on the same principles as the Argen- 

 tine case above described. The case proper is built of selected lumber and is 

 293^ inches long, 20 inches wide, and 15 inches high, outside measurements. It 

 is so similar in construction to the Argentine case that, aside from a general 

 description, only the diff^erences between the two will be pointed out. 



The German-Chile case accommodates two stacks of trays 7 K^ by 83^ inches, 

 in a double-chambered compartment having walls of unperforated galvanized 

 iron, which is strengthened by a heavy wire around the top edge. A removable 

 metal partition separates the two stacks of trays. The compartment itself is 

 made one-fourth inch larger each way than the tra}- frames, to allow for swelling 

 and the binding twine which will be placed around the trays. Next to and 

 surrounding the tray compartment is the ice, outside of which is the dry moss 

 or other nonconductor, within wooden walls, the same as in the Argentine case, 

 while resting upon the top of the trays and ice compartments is an ice hopper. 

 For purposes of insulation the ice in the hopper is covered with a cushion filled 

 with dry nv)ss, oilcloth being placed between the cushion and the ice. The 

 metal bottom of the hopper has perforations only over the trays, that the eggs 

 may receive the benefit of all drip water. Small cleats are fixed at either end 

 of the ice hopper to facilitate handling. Under the tray compartment and 

 coextensive with it is a perforated wooden false bottom to the case, between 

 which and the bottom proper is a i-inch air space. A drain hole is provided in 

 the bottom proper. The egg trays are made a trifle deeper than the diameter 

 of the eggs; and the latter are placed on them a single layer deep without any
