Dissemination of Seeds of Osage Orange. The editor of the American 

 Botanist invites readers to suggest explanations concerning the method of 

 seed dispersal in the case of the osagc orange fruits, which are so sticky and 

 disagreeable as to repel all grazing animals. Rolling is one apparent explana- 

 tion, and floating on water another. 



Gipsy Moth. An abbreviated account of this insect, which many 

 entomologists consider the most dangerous ever introduced into America, has 

 long been needed and is now supplied as Farmers' Bulletin 275 (free, Dept. 

 Agriculture, Washington). Every nature-study teacher who deals with in- 

 sects should read this pamphlet. 



The animal has now spread from the vicinity of Boston to 2480 square 

 miles of Massachusetts, also in the sea-coast towns of New Hampshire, in 

 a 'i^w places in Maine, Rhode Island and Connecticut. In 1900, when the 

 Massachusetts State Board of Agriculture after ten years' work was compelled 

 to stop because the legislature did not make an appropriation, the insect was 

 restricted to 360 square m^les. Five years of inactivity ( 1 900- 1 905 ) resulted 

 in the great spread to the areas named above. Three hundred thousand dol- 

 lars have been appropriated by Massachusetts for 1905,1906, 1907; ^30,000 

 for experiments with enemies; 20 to 50 per cent of cost of the fighting the 

 moth must be paid by cities and towns; owners of property must destroy 

 eggs, pup^, and nests; Congress at its last session appropriated ^82,500 to 

 prevent spread of the gipsy and brown-tail moths; and bills will be introduced 

 into the present legislatures of the other States to which the gipsy moth has 

 spread.
