 lowing species. Dates of flowering : March 27, 1903 ; 

 March 27, 1908; March 31, 1909; March 26, 1910;

 small clusters along the twigs. 



The Sweet or Mazzard Cherry (Prunus avium L.), the common 

 sweet cherry of the orchard and a native of the Old World, is spon- 

 taneous in Chapel Bill and no doubt in many other places in the 

 state. The Sour or Morello Cherry (Prunus cerasus L.) is probably 

 also spontaneous hi some parts of the state.
