(6.) Protect the box of moss which contains the eggs from 
changes of temperature by a competent outer packing of sawdust, 
or some other non-conducting material, to keep the heat or 
extreme cold to which the package may be subjected from 
reaching the eggs within. 
(The author thinks that moss is the best material for the 
outer packing, but does not here insist upon it.) 
(7.) When exposure to warm air is to be guarded against, 
wt 7s necessary to provide ice-chambers in the outer packing- 
boxes.. As this,is, merely .avpqueéstion ot-)mechanical cone 
trivance,.I will not enlarge upon at here any further than 
to say that the ice-chambers should be so arranged that the 
water and the cold coming from the melting ice should be 
allowed to descend upon the eggs. 
(8.) By all means, tf ice ts used, have apertures in the top and 
bottom of the egg-boxes to let in and let out the water 
caused by the melting ice. The openings at the top let the 
ice-water in to the eggs, which cools and refreshes them; 
while, on the other hand, the openings at the bottom let the 
water out, which is absolutely indispensable, as there is 
nothing more surely fatal to salmon-eggs than stagnant 
water. 
If the above directions are carried out, it makes very little 
difference what the size of the packing-boxes is, or the 
shape or the material, provided they are clean, strong, con- 
venient, and suitable for general packing purposes, it being 
desirable only to remember that the depth of the boxes con- 
taining the moss and eggs should not be over six inches. 
For the benefit of inexperienced amateurs in fish-culture 
I will repeat the programme for packing eggs, so well 
known to all professional fish-culturists, viz.: Place at the
