well if moderately agitated, and that it is not easily washed off the leaf 

 surface. Disadvantages are its larger cost and the fact that it does not

Hellebore 



Hellebore 1 ounce 



Water 1 gallon 



or 



Hellebore 1 part 



Flour 3 parts 



Hellebore is a white powder, consisting of the finely ground roots of 

 the plant known as white hellebore {veratrum album). It is of little 

 value unless it is fresh, or has been kept in a tightly closed vessel. It 

 is poisonous to the larger animals when taken in sufficient quantity. 



It may be used dry or as a spray. If it is to be used dry, mix it with 

 flour at the rate of one pound of the powder to three pounds of flour, 

 and let the material stand over night in a closed vessel. It may then 

 be dusted on the plants in any convenient manner. There is no dan- 

 ger of burning the foliage. If to be used as a spray, steep one ounce 

 of the powder in one gallon of water. 



Hellebore has the advantage that it loses its poisonous properties 

 after exposure to the air for three or four days, and therefore may be 

 applied with safety to ripening fruits ; for example, currants that are 

 about ready to use.
