ance. If enclosed in a packaf^^e wet they are likely to become 

 mouldy before arrival, and this is very undesirable. Roots 

 j^hould 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 speci- 

 mens. Give the condition of the plant or crop, the variety, 

 its age, length of infestation, soil, nature of the present sea- 

 son, kind of culture, estimated monetary loss, etc.

DUCK EGG IXCUBATION. 



The method of incubating duck ego:s as practiced by the Chi- 

 nese of Hawaii is somewhat peculiar. A special room is de- 

 voted to this use, within which a bin is built, about three feet 

 high, running round the room. Within this receptacle are 

 placed ordinary wooden barrels lined with feit paper The 

 eggs to be hatched are spread on trays in the sliu uu!;1 they 

 attain a temperature of from 102 to 103 degrees. Thev are 

 then placed in the barrels layer upon layer, a thin cloth being 

 inserted between each, and a heavier cloth covering the wdiole. 

 The eggs are turned regularly by removing the lavers of cloth 

 one by one, with eggs upon them, and by replacing first the 

 one taken from the top of the barrel. At the oroper time the 

 eggs are removed from the barrels and placed upon trays on 

 racks above the bin. As soon as they are hatched the young 

 birds are sold to the large ranches, at the rate of about $50 per 

 thousand. 



THE 'TAP AW" OF THE UNITED STATES. 



The two cultivated and six wild species of Eastern North 

 American shrubs and small trees, to which the name ''papaw" 

 is commonly applied by the Americans, are species of Asimina 

 (natural order Anoiiaceac) closely related to the sweet sop or 

 sugar apple of the tropics. The two cultivated species bear 

 attractive flowers and edible fruits. Otie will grow in the 

 open in New York State. The true papaw of the tropics, 

 Carica Papaya, is not in anv way related to the above-m. :?n- 

 tioned species. It is called in the United States ''melon 

 papaw'' for the sake of distinction. It grows in the open nr\\y 

 in South Florida ; but is frequentlv in conservatories nortli rf 

 the frost line. — The Agricultural News, Barbados.
