Cherry Trees, Disease of (Die Gart. p. 375, May 9, 1903).— For some 

 years the Cherry trees along the Rhine have shown signs of decay, even 

 young trees having an unhealthy appearance. Experts have found that 

 the trees have suffered through late frosts exposing them to the attack of 

 a fungus — Valsa leucostoma. The fungus first gets a footing at the 

 small branches of the frozen wocd and slowly spreads to other parts, 

 ultimately killing the whole tree. Cutting away the branches affected 

 with the disease when in its early stages, and putting tar over the wound, 

 will often save the trees frcm destruction. — G. B.
