tying up or enclosing each midwinter plant as it stood in 
the bed. Tiles placed about the plants—which are so 
successful in the field,— rotted the plants in the moist air 
of the forcing-house. Heavy bibulous paper did the 
same. But thick, hard wrapping paper, with an almost 
‘‘sized”’ surface, proved to be an admirable success. 
The stalks were brought together and tied, and a width 
of paper reaching to within 2 or 3 inches of the tips 
of the leaves was rolled tightly about the plant. As 
the plant grew, another width of paper was rolled about 
the first, and again reaching nearly the top of the plant. 
Two applications of the paper are sufficient. A month to 
six weeks is required to bleach the celery by this process 
in a cool house in April and May. Fig. 45 (page 140) 
shows the method of bleaching with the paper. 
The seeds for one of our crops of house celery were 
sown December 10, 1894; pricked off, January 8; planted 
in beds, February 6; first tied up in paper, April 12; 
second tying, May 9; celery fit to use, May 21 to June 20. 
The Kalamazoo celery is well adapted to house cultiva- 
tion The quality of this house-grown product is equal to 
that grown in the field.

Water-cress.— Persons who are fond of water-cress 
should know that no plant is easier to grow under 
benches in greenhouses. If there is an earth floor under 
the benches of a cool or intermediate house, the plant 
will take care of itself when once introduced, provided, 
of course, there is sufficient moisture. Fig. 46 (page 
142) shows a mat of water-cress growing under a bench 
in a general conservatory house, near the overflow of a 
tank. It is not necessary to supply water in which the 
plant may grow, but it thrives well, with its characteristic 
flavor, in soil which is simply uniformly moist and cool. 
The plants may be gathered from brooks or other places
