In this first number insect injuries are omitted; they are 
to be included in succeeding years. The diseases treated are 
described in such a way that a man of average intelligence will 
be able to identify most of them without the aid of even a hand 
lens. In the case of the more important diseases directions for 
combating them are given. The subject is arranged in nine 
chapters, according to the host plants, as follows: I, Cereals; 
II, Grasses and forage crops; III, Vegetables and garden plants; 
IV, Fruit trees; V, Berries; VI, Grapes; VII, Forest trees; 
VIII, Garden and ornamental plants; and IX, Tropical and sub¬ 
tropical plants. Four indexes close the work, viz, host and 
parasite indexes in both Russian and Latin. 
I. CEREALS. 
Wheat. — Tilletia tritici Wint., attacking especially winter 
wheat, and Ustilago tritici Jensen, principally on spring wheat 
were abundant over all Russia, especially, however, in the South- 
Central governments. Ergot, Claviceps purpurea Tul., was abun¬ 
dant in Kursk government. Of the three rusts, Puccinia graminis 
Pers., P. glumarum Eriks. & Henn., and P. dispersa Erik. & 
Henn. the second was rare, the third abundant, especially in the 
central governments, while the first was very abundant in 
these governments and especially in Caucasus where in some 
regions the crop was totally destroyed. Low-lying, shallow clay 
soils were most subject to the disease. 
Rye. Ergot, Claviceps purpurea Tul., was a very serious 
pest, being very abundant in Western Siberia and in Central and 
Western Russia. In one district in Poland 33% of the grains 
were affected. Stem rust, Puccinia graminis Pers., was less 
abundant than usual, except in Kovno government where it was 
unusually severe. Brown rust, P. dispersa Eriks. & Henn. oc¬ 
curred more or less abundantly in Central and Western Russia. 
Oats. Ustilago avenae Rostr., was not abundant in Northern 
Russia, but in the South was destructive, as well as in the East. 
In Simbirsk government the variety Datsky was especially se¬ 
verely attacked. Puccinia graminis Pers. and P. conorifcra 
Klebh. although occurring, were nowhere very destructive. 
Barley. Ustilago hordci Bref. was scarce in 1903 although 
in 1901 it was abundant in many districts. Puccinia graminis
