50 GENERAL CONCLUSIONS. 



of good form to seed from ; for, as running to 

 seed, multiform top, forkiness, " finger-and-toe" 

 in roots, is evidence of wild growth, so, then, 

 cultivated plants assuming this form are con- 

 sidered as degenerate, and seed from such roots 

 produces a malformed and poor crop. 



Fifth. — The difficulties of getting good seed — whether 

 of trueness to sort, from carefully selected bulbs, 

 or free from adulteration either of old with new 

 seed, or a mixture of charlock and others of the 

 same family — are very great. Where, however, 

 good seed can be depended upon, it is much 

 cheaper, though at a considerable increase of first 

 seeds cost, as not only quality but the quantity of 

 live so considerably depends upon the truth and 

 honesty of the seedsman. 



Sixth. — Injuries from insect attacks, though serious 

 as affecting the yield, are yet not due to the 

 seed; and anbury, if it be due to insects, only 

 occurs in the turnip-crops, and then in parti- 

 cular soils. The true insect attacks to be averted 

 by simultaneous action. 



In fine. — Good seed, of a true sort, — care in growth, 

 — and a watchfulness of enemies, includes the 

 Science and Practice of Boot Cultivation.
