lu one instance a leaf spot cUie apparently to Ctrcosporu sp. 

 has been collected. The spots were small (two to three millimeters 

 iii diameter) amphigenous, circular to angular, without a definite 

 margin, dull brown to gray, often coalescing and causing a yellowing 

 and subsequent death of the leaf. Fruiting on both surfaces. Co- 

 nidia hyaline, long clavate, strongly septate. If, as appears certain 

 now, this species is undescribed, a complete description a)id name 

 will be ])ublished later, together Avith more complete notes on the 

 nature and amount of injury caused by it. 



Peanut {Aradiis hypogea). 



The peanut was subject to two leaf diseases, both quite etrective 

 at times in reducing the yield. Other diseases due to Sclcroiinm 

 Bolfsii, or to other root-rot or wilt inducing fungi, have not been 

 observed, but doubtless occur, or will with any extension of planting. 



Leaf Spot (Cercospora personaia) . — The leaf spots caused by 

 this fungus were nearly circular, brown to black with an indefinite 

 margin, and generally numerous enough to practically cover the leaf 

 surface. The lower leaves were attacked first, but the others soon 

 succumbed in turn. It was difificult to estimate the damage, some 

 growers declaring that the disease appeared after the crop was prac- 

 tically mature and that hence no damage was done. 



Rust (Uroynijces arachidis). — This fungus attacked all varieties, 

 causing innumerable small golden brown to dark-bi-own pustules on 

 both sides of the leaves, in many cases practically covering them and 

 undoubtedly doing some harm since the effective leaf surface was 

 reduced. In fact, experiments in the British West Indies have shown 

 that decreased yields do result from attacks of this disease. Spray- 

 ing with Bordeaux at intervals of a week was reported to h;i\c been 

 Avithout effect in checking or controlling either of these diseases. 



Pepper {fapsionn (nnnniDi). 



I-'kiit Kdt. — The peppers of the fii'st planting (Neai)olitan) re- 

 mained comparatively free of this trouble, but those of the second were 

 seriously attacked. These varieties were Sweet Mountain, Large-bell, 

 -Chinese Giant and Ruby King, all of which were attacked to about 

 -thu same degree, in so far as preliminary observations of one year 

 show. At the time the first picking was made a large percentage 

 of the fruit was found to have on one side or at the blossom end 

 rotted areas. These were in general medium to light brown in color 

 or at times nearly white, with definite margins and often sunken.
