SELECTION OF PLANTS 39 
some of the stools having as many as eight or ten, but all very 
weak. One stool died after growing two heads. 
Third Year.—No. 1.—Magnificent growths, the heads 
measuring on April 1oth from two inches to three and one- 
quarter inches in circumference. 
No. 2.—Growth passable only, but very irregular. Some 
of the stools were very small. The finest of them produced 
heads which from April 8th to toth only measured two and 
one-half inches in circumference. 
No. 3.—Growth very poor and very irregular. Some of 
the stools continued to produce small heads not much thicker 
than a quill pen, the largest being from one and one-half inch 
to two inches in circumference. 
fourth Year.—No. 1.—Growth very remarkable. The 
heads began to show on April 3d, 4th, 5th, 7th, and roth. 
Some were from three and one-quarter inches to four inches in 
circumference, and measured four and three-quarter inches. 
Fifty of the heads formed a bundle which weighed seven pounds. 
No. 2.—Growth passable, but laterthan No. 1. The heads 
made their first appearance on April 6th, roth, and 11th. 
Many of them were very small; fifty of them barely made 
half a bundle, and only weighed three and three-quarter 
pounds. 
No. 3.—Growth but poor, and somewhat late. The heads 
made their appearance on April 4th, 6th, 9th, and 11th; one 
did not show till the 22d. Fifty heads barely formed half a 
bundle and only weighed two and one-half pounds. 
To sum up, it is clear that the plants of a year old in their 
fourth season—that is to say, after having been planted out 
for three years—gave a bundle weighing seven pounds, while 
those of two years old only gave three and three-quarter 
pounds, and those of three years old only two and one-hal 
pounds ; in other words, taking round numbers, the planta- 
tion made with the one-year-old plants produced double the 
crop of the two-year-old plants and treble that of the three- 
year-old plants. The reader may easily draw his conclusions 
from the preceding facts.
