Miss B. writes:
"Let me relate my experience. Three years ago I gathered some seeds of Golden Pyrethrum, and planted half the next spring. Not one came up. I supposed they were not ripe. Yet unwilling to give up trying for the beautiful plant, the following spring, more than a year after they were gathered, I planted the remainder of the seeds, and sprinkled the earth with camphor-water. They all came up. Slips which have traveled thousands of miles, and apparently have no vitality, when soaked in camphor-water grow green and fresh".
