onion leaves, if allowed to rot on or in the 

 ground, give rise to resting spores, which 

 have a remarkable vitality, and are able to 

 set up a fresh attack if their host plant, the 

 onion, is grown in the same soil within two 

 or three years. 



BUD DROPPING IN SWEET PEAS. — 

 J. E. T., Chesterfield: Can you tell me w^hy 

 my sweet peas do not develop properly be- 

 yond the bud stage ? They appear to be 

 quite healthy, and the buds look well until 

 it is tim^e for them to open, when they turn 

 yellow and fall. I am enclosing a few speci- 

 mens for your inspection. The plants are very 

 robust, about six feet high, and the leaves 

 are deep green. They have had only farm- 

 yard manure, trenched in about three feet 

 deep, two monthi^ before planting time, but 

 they have been watered onjce with weak 

 liquid manure. Tlie ground had previously 

 been occupied by apple trees, which were 

 dug out lacit year. — Judging from the appear- 

 ance of the stems and foliage of the speci- 

 mens sent, the soil in which the sweet peas 

 are growing needn a considerable addition 

 of lime and potash, both of which are very 

 necessary to the succest^ful ciiltivation of 

 sweet peas. It is rather late in the season 

 to do anything that will be of very great 

 benefit to the plants, but sulphate of potash 

 used at the rate of loz. to each gallon of 

 water, given once a week at the rate of two 

 gallont^ per yard run, may be of service. 

 Give a good dressing of lime between the 

 rows, and lightly prick it in with a fork. 



ROCK TOBACCO.— L. N. N., Maidenhead, 

 asks whether we, or any of our rea'ders, know 

 the Rock Tobacco, and can say whether it is 

 hardy^ or not ?— The Rock Tobacco is Primu- 

 lina Tabacum, a low-growing Cliinese peren- 

 nial of doubtful hardinesK. It has purple, 

 primula-like flowers, and if the fresh leaver 

 are gently drawn between the hands thev 

 exhale a strong tobacco-like fragrance. If 

 any of our readers liave had experience with 

 this plant, we shall be glad if they will send 

 U5 a note concerning its cultivation. 



SOLUTIONS OF COPPER SULPHATE 

 — M. E. F., Saffron Walden : I shall be 

 obliged if you will inform me how to prepare 

 solutions of co]>por r>ulphate, such a.> are 

 used for spraviiio- faim crops to check cer- 

 tain weeds.— To make a 2 per cent, solution 

 of copper sulphate, 81b. should be dissolved 

 m 40 gallons of water; for a 4 per cent, solu- 

 tion, 161b. in 40 gallons of water. To pre- 

 pare a 15 per cent, solution of sulphate of 

 iron. 601b. must be dissolved in 40 P-allons of 

 water. In either case 40 gallons of solution 

 will suffice for an acre of the cereal crop 

 To dissolve the sulphates of copper or iron 

 the powdered material .should be placed in a 

 bag and suspended in the water by tying the 

 top of the bag to a rod placed across the 

 mouth of the barrel or tub containino^ the 

 water. Warm w^ater and frequent movement 

 of the bag will aid solution.
