AGE AT WHICH SEED MAY GERMINATE, 
Under favorable conditions of harvesting and keeping, 
some varieties of vegetables may retain their germinative 
vitality through many years, and some seed, such as tomato 
seed, may be as useful at ten years of age as when younger. 
To illustrate the limit of age for influencing vitality, we 
select for certain varieties the highest figures of germina- 
tion obtained in the case of seed several years old. For the 
material used in this study we are largely indebted to J. M. 
Thorburn & Co., seedsmen of New York city, whose relia- 
bility amply justifies our assumption of correctness in the 
ages as given, and who kindly forwarded to us seed in 
packages marked with the year of growth. We add ina — 
parallel column the germination limit as given by Messrs. 
Vilmorin, in their Les Plantes Potageres, Paris, 1883.
