From experience at this station it appears that such a con- dition may follow the use of any soil that is not sweet. An instance occurred when a mold growing over the ashes of a bench entered the bottom of some pots of peas, causing the soil to become stale and musty. All the plants where this occurred showed streaked foliage later. The disease is undoubtedly physiological in its nature and is thought by practical growers to occur sometimes from the use of too much or too fresh manure on young plants. The dropping of flower buds is often a cause of complaint from growers. The first flower buds frequently do not set on vigorous, thrifty plants. Usually this condition soon disappears, but sometimes it is necessary to keep the plants a little dry and to abstain from the use of fertilizers until the plants are blooming freely. The loss of the buds will follow a sudden fall in the temperature or will result from over- watering. Another cause is growing the plants in too cool an atmosphere. Plants that are grown in the proper temperature, with careful attention to watering, ventilation and feeding, do not fail to give an abundance of flowers. Mildew sometimes attacks sweet peas during the autumn, unless the tempera- ture and ventilation receive attention. It has been found at this station that mildew yields readily to applications of sulphur to the pipes, and to the use of flour of sulphur dusted on the infected leaves. As soon as the fires are started in the fall, some sulphiir should be ap- plied to the pipes as a preventive. This should be used judiciously, however, for an interesting case came under observa- tion at this station dur
