NEW WAREHOUSE AT DREER'S RIVERTON NURSERY. question of the amount of loss result- ing from this disease is hard to solve. As all varieties are more or less sub- ject to this disease we can run no rec- ord tests to determine the actual amount of loss, so that we must resort to mere observations which is not al- ways satisfactory. The direct loss, as figured from the standpoint of flower production, is not great. However, the quality of the flower is lowered directly as the vitality of the plant from "yel- lows" is lowered. The indirect loss from "yellows" is considerable. Observation shows that this disease lowers the vitality of the plant, and with lowered vitality fungi, especially branch rot, attack the plant causing a very noticeable loss. Branch rot, which is primarily a wound fun- gus, cannot attack a healthy plant, but is able to kill a weak plant in a short time. During certain seasons of the year this disease appears to be more no- ticeable than at others. In the cut- ting bench, cuttings showing "yellows", as a rule do not strike root easily, while apparently healthy cuttings ta- ken from plants showing this disease root poorly. The disease is very marked when the rooted cuttings are potted up and for several weeks the young plants show considerable "yel- lows", which apparently disappears by the time they are planted in the field. During July and August the plants in the field again show this trouble worse. During the winter months "yellows" increases on the plants in the house until spring, when the disease is at its height. At the time of making cuttings the disease is evident and so can be avoided to some extent in the selection of cuttings. Cuttings have been selected now through three seasons, and the results show that by selecting cuttings from healthy plants only, we can control the trouble to some extent. One ob- jectio
