For many years the forcing of tomatoes and cucumbers 

 for winter marketing has been quite profitable near some 

 of the large markets, but at the present time, there are 

 fewer inducements to engage in the business than formerly, 

 owing in part to the low prices at which the southern 

 growers' crops can be placed on the northern market and 

 the competition from the large number of persons who are 

 now engaged in the business. During the spring and 

 early summer after the time when lettuce can no longer 

 be grown with success in the houses, there is still an op- 

 portunity of growing both of these crops with profit, as 

 the houses can be used for nothing else at this time and 

 there will be but a small expenditure for fuel. In the 

 winter, however, the expense of keeping up the necessary 

 high temperature in the houses will be very large and the 

 prices sometimes run very low, but, with good care, fairly 

 profitable returns will be secured. In order to secure the 

 development of fruit upon most of the common varieties 

 of cucumbers artificial fertilization of the flower must be 

 resorted to, when they are grown in forcing houses during 

 winter, unless a hive of bees is placed in the house for the 

 purpose of carrying the pollen from the staminate flower 

 to the pistils. It can be done by taking the pollen upon 

 a small brush and dusting it over the pistils. 



VARIETIES. 



For most markets the common garden varieties are the 

 only ones that are profitable, the White Spine and a strain 

 known as Arlington White Spine, being most commonly 

 used. The plants are also subject to attacks of various 

 fungous diseases, one of the most injurious of which is the 

 powdery mildew. 



For diseases of this kind, evaporated sulphur will be 

 found an excellent remedy. There are a large number of 

 other varieties of vegetables grown under glass by those
