Articles of botanical interest in this Bulletin may be found 
under the headings ‘“ Fungus Diseases,” “‘ Weed Pests,” ‘“ Pre- 
liminary Report on the Examination of Some Seeds,” and “ Notes 
on Some Methods of Cross-Pollination.” Subjects of illustration 
under the first are: Gymnosporangium macropus, Puccinia Prunt- 
spinosa, Septoria Ribis, S. Pruni, S. Ravenelit, Spherella Grossu- 
larie, Phyllosticta Pyrina, Cylindrosporium Padi, Fuscicladium 
dendriticum, Uromyces Trifoltt. A weed is aptly defined to be 
“a plant out of place,” and as such the purity of seeds sown for 
farm crops is of great importance. Where crop seeds are adul- 
terated by those of weeds it is of the highest importance to be in- 
formed of the fact, and this has been the subject of examination 
on the part of Mr. P. H. Rolfs, with interesting results which are 
set forth in his “ Preliminary Report” upon the subject. For 
example a pound of “ Sanfoin”’ (Oxobrychis sativa) was found to 
contain twenty-nine different kinds of weeds! — Pi: FA.
