2, 3, 4, 5, 6, are annual plants, and must be increased by 

 seeds, which may be sown in the spring ; — or in autumn, 

 sheltering them in the winter ; with the exception of the 

 last, which should be sown in March, and will require no 

 shelter. 3, 4, in five-inch pots: 6, three or four seeds 

 in an eight-inch pot. 



7, 8, 9, 10, are perennial plants ; they may be sown as 

 the last mentioned, in spring, or in autumn ; they will 

 require shelter from hard frost. The two last may also 

 be increased by parting the roots in autumn. The com- 

 mon-yellow is an indigenous plant, and if in a tolerably 

 dry soil, will bear frost itself: a little straw over the roots 

 will suffice for 8. In Worcestershire the common yellow 

 toad-flax is called butter-and-eggs. It has leaves somewhat 

 similar to flax, and on that account is named toad-flax, 

 flax-weed, and wild flax. Its juice, mixed with milk, is 

 used as a poison for flies ; and water distilled from it is 

 said to remove inflammation in the eyes. 



11, 12, may be increased by cuttings, planted in the 

 summer in a light unmanured soil. They must be removed 

 into the house in October, and brought out again about 

 the end of April, or early in May.
