with certain iiicthcKls of transplanting. The disease on tomatoes 

 does not destroy the foHage of the plant, but the abnormal meta- 

 bolic processes which api^ear to be associated with this disease 

 apparently affect the yield. A thorough study of this trouble is 

 now being made in our greenhouse by Mr. G. H. Chapman, ^ and 

 will be reported on later.

SOIL CONDITIONS FOR TOMATOES 



The nature and conditions of the soil in which tomatoes are 

 grown has much to do with the size of the crop and health of the 

 plants. Plants grown in rich loam, of good texture, will develop 

 a dark green color and luxuriant grow'th of foliage, w^hereas those 

 grown in a poor soil will be light in color and spindling in ap- 

 I)earance ; moreover, feeble plants are much more susceptible to 

 disease. We have repeatedly observed that the best crops are 

 obtained the first year and that in succeeding years the crops
