Moist, warm weather is the best condition for the growth of blight.

On the opposite page is an illustration from a photograph taken from a field showing the dissemination of blight. Near the bottom is the center of dispersion. If the plate contained more of the field it would show the rest of the blighted spot to be similar to the above portion.

Egg-Plant.

The egg-plant shows a yellowing of foliage, and the plan looks sickly. The lowest leaves fall off and leave the stem exposed Finally the fruit begins to fall off.

If heavily attacked, a wilting, similar to that of the toma takes place. There are no spots or other characters to tell t blight. A typical diseased plant is shown in plate II.

Irish Potato.

The Irish Potato acts much like the egg-plant when at tacked by blight. The leaves are not dropped and the plant i more tenacious of life.

The attacked plant at once sets a great number of tubers, which rarely get larger than peas or hazel nuts. It looks rather urious, when carefully dug, to see a number of larger tubers, bout the size of a hen's egg, at the proper distance from the tem, and then a great lot about the size of peas clinging closely o the stem. The potato tuber is one of the most prolific sources o propagate the blight. It is, however, only attacked when near he surface or on top of the ground.

Beans and Cow Peas.

The various varieties of beans (Phaseolus) and the cow pea Dilochos) suffer severe loss in all stages of growth. The young cow ea, or bean, usually dies before the blight matures, but the bearng plant is a fertile field for its reproduction. The cow peas and beans act very similarly when attacked by blight. The leaves
