anything that may cause a weak leaf-action of the plant, too much water 

 in the soil, and too much moisture in the house, especially during the 

 night.

Evaporated sulphur proved beneficial, but not wholly preventive, in 

 fact, only preventive conditions were found satisfactory. These condi- 

 tions are: 



1. A lower temperature at night than during the day, i. e., ranging 

 from 350 P. to 450 F. at night to 50° F. to 70° F. during the day. In 

 sunny weather the tempei'ature may run 10° to 15° higher than on 

 cloudy days. 



2. Perfect drainage of the soil. 



3. A house naturally dry, light, and airy. 



4. An abundance of plant-food in a light porous soil. 



Should the plants not start into a vigorous growth soon after trans- 

 planting, the application of flue ground bone, one-half pound to a square 

 yard, and 2 ounces of nitrate of soda to the same space, will give remark- 

 able results. 



Suggestion. — While it is possible by close and constant attention to 

 provide conditions for the successful growth of both the rose and lettuce 

 under glass, such care and attention adds very materially to the cost 

 of the products, and some means should be devised to destroy the germs 

 of these diseases. This may possibly be found in fungicides used in the 

 houses, before the plants are started or by their application to the soil 

 and growing crops while in a young state.

TREATMENT OF CRANBERRY SCALD AND CRANBERRY GALL- 

 FUNGUS. 



By Byron D. Halstbd. 



It has been determined by a thorough canvass that a large fraction of 

 the cranberry crop is destroyed by the scald, sometimes called " rot." 

 The loss sometimes reaches as high as 65 per cent., and in many places 

 it has rendered the growing of cranberries a profitless industry. 



A fungus is closely associated with this scald, and in no case has a 

 soft berry been examined microscopically without the same fungus 

 being present. The leaves, vines, and roots also of the plants bearing 

 scalded berries, abound in the same fungus. In general structure, hab- 

 its, and behavior, the fungus of the cranberry scald is closely related 

 to the one causing the black-rot of the grape. As yet no fungicides 

 have been tested upon the scald, but from its relationship to the black- 

 rot of the grape it is only reasonable to infer that the same treatment
