day, allowing the temperature to rise to 115 or 120 Fahr. and 

 the author has never known this remedy to fail. 



On one occasion last season, the disease made its appearance 

 during a spell of dull weather, and several days elapsed before a 

 bright day appeared, and then only a temperature of 103 Fahr. 

 was obtained, which had practically no effect. 



Several days later, a temperature of 120 Fahr. was reached, 

 and the result could be seen almost immediately. The disease 

 was cured, and all the affected plants commenced to grow again, 

 although the old scars .remained ; but these soon became healed, 

 like wounds on the trunk of an actively growing tree. 



The temperature necessary to eradicate the disease appears to 

 be about 115 Fahr. Care should be taken that the roots are suf- 

 ficiently moist, as such high temperatures cause excessive trans- 

 piration, and, if the roots are at all dry, burning results. The fo- 

 liage should not be thinned excessively before shutting up the house, 

 and if some of the more exposed fruits are slightly shaded from 

 the direct rays of the sun, it is an advantage, as the author has 

 occasionally had a fruit, here and there, scalded. 



British tomato houses are not shaded in any way, and the ther- 

 mometers from which the above temperatures taken were more 

 or less in the direct rays of the sun. The houses are not opened 

 until the following morning, to allow the temperature to fall gra- 

 dually, as a sudden change to colder conditions might have serious 

 effects. 



American Gooseberry Mildew. Journal of the Board of Agri- 

 culture, May 1909, n. 2, p. 117. 



A description is given of the Gooseberry disease. The following 

 extracts are of special interest to the "general reader: 



The disease known^as American Gooseberry Mildew, Sphaero- 

 theca Mors-uvae, Berk., is of a very serious character. It has greatly 

 increased the cost of the cultivation of gooseberries wherever it 

 has appeared, and in some cases it has rendered gooseberry-growing 

 impossible. 



This fungus is much more injurious to gooseberry bushes than 

 the allied European Gooseberry Mildew, Microsphaera Grossulariae, 

 LeV., as it not only attacks the leaves, but also extends to the shoots 

 and fruit, stunting the latter and rendering it unsaleable.
