in transit, in which case it may be advisable to puncture the tin 
with a few small holes. 
As a rule, roots should be sent with the soil attached. 
Never send fresh specimens in an ordinary envelope. Some 
specimens, such as dried leaves and bark, may be sent in this 
way if wrapped in several folds of soft cloth. 
In case any special method is necessary the empty package 
and the necessary preservatives will be forwarded free, by post, 
after the receipt of specimens in the ordinary way proves in- 
effective. 
Bottles containing fluid should be enclosed in boxes in packing 
material so as to exclude all possibility of breakage. 
Specimens of leaves or twigs sent in their natural condition 
should not be gathered when wet, or, if gathered wet, should be 
allowed to dry until they resume their dry-weather appearance. 
If enclosed in a package wet they are likely to become mouldy 
before arrival and this is very undesirable. Roots should be 
moistened a little — just enough to preserve them in their normal 
condition until they arrive in Honolulu. 
It is very desirable that notes should accompany the specimens. 
Give the condition of the plant or crop, the variety, its age, length 
of infestation, soil, nature of the present season, kind of culture, 
estimated monetary loss, etc.

SCABBY POTATOES. 
Much has been said about scabby potatoes and yet there are 
very few people who really know what they are. The scab is a 
fungus disease, similar to the blight on rose leaves or the rust on 
the stem and pods of beans. The spore-threads of the fungus 
cause the skin of the tuber to become rough and pitted. The 
fungus spreads very rapidly and potatoes although apparently 
clean when first stored, if only slightly scabby, will become badly 
diseased after a very short time. 
Scabby potatoes are very prevalent in many States and for a 
number of years all shipments of potatoes coming to the Islands 
have been carefully watched and all shipments showing such 
infestation were refused entry. 
•The potato industry of the Islands is not very extensive as yet 
and still we have many areas on which good potatoes can be 
grown and which no doubt will be equal if not superior to the 
bulk of the shipments arriving here. Therefore great care 
should be exercised by every grower of potatoes to see to it that
