leaving It uncovered. Allow them to freeze, leaving them 
In the vessel until Spring. Drive nails as large as gin- 
seng seeds in a plank, making them about 1 inch apart. 
Use this to plant the seeds regularly about five-eighths 
of an inch in depth. Place a seed in each hole and cover 
lightly with the hand. The rows should be about six 
inches apart. Spray with a very fine stream of water twice 
a day. Allow the planted seeds to receive the sunlight 
until the sprouts appear. During all of this time the 
beds should be protected from rains but sprayed regularly 
twice a day. The soil should be kept in good condition by 
hand cultivation after the young plants come up. This 
care must be constantly given to the plants. The plants 
are taken up at the time they are about one year old and 
only the best ones are saved for transplanting. Many 
planters do this each year for six years after the plant 
comes up. others transplant and select for only the first 
two or three years. The plants are planted out about 6 
Inches apart and in rows about 1 foot apart. Care must be 
•taken to give the two regular waterings each day during 
the growing seasons. (Gist Gee.) For distribution later.
