This strawberry is thus described by Mr. M. Crawford, the great Ohio straw- 

 berry cultivator : — "Color, bright glossy red ; texture, firm and quality good. The 

 trusses are large and spreading, the blossoms bisexual, and the plants dark green, 

 strong, stocky and perfectly healthy." He adds, " What I have seen of the 

 Parker Earle corroborates my former opinion that it is an acquisition." 



PLUM LEAF OR SHOT-HOLE FUNGUS. 



~>k URING this last season much curiosity was awakened by the peculiar 

 aI appearance of many of the leaves of our plum and cherry trees. They 

 were full of small round holes, for which there was no apparent cause. 

 We looked in vain to find an insect, to which the damage might be at- 

 tributed ; but the mystery is explained by the following article by Prof. 

 Scribner, on the fungus Septoria Cerasina, in Orchard and Garden. This 

 fungus is very generally distributed throughout the States east of the 

 Mississippi. It attacks the foliage, and although not regarded as a serious 

 pest, it often inflicts considerable injury both to the 

 cherry and plum, by interfering with the proper 

 functions of the leaves, or by causing these to drop 

 prematurely, sometimes as early as the first of August* 

 The leaves attacked show, at first, scattered here and 

 there over the surface, dark purple spots, visible on 

 both sides, varying from 1-24 to 1-8 of an inch in 

 diameter. After a brief period it will be noticed that 

 the tissue covered by some of these spots has become 

 dead and brown in color. Such spots usually have 

 their margins clearly defined, and are most often cir- 

 cular in outline. Sometimes this dead tissue drops 

 out from the leaf, leaving a clear cut, round hole, 

 giving the leaf the appearance of having been perfor- 

 ated by shot holes, hence the name sometimes given 

 to the disease, mentioned above. 



If we examine one of the brown spots under a 

 lens, we will usually detect upon the under surface 

 one to several very minute black points. These 

 points are the fruits of the fungus-little capsules, with- 

 in which the spores of the fungus are produced in 

 great abundance. They, the spores, are very slender, 

 many times longer than broad, and quite transparent.
