MONTHLY SUMMARY. 575 



a sandy soil, and witliout mucb, if any, maunre; there "will, how- 

 ever, be no harm in his giving it the ordinary preparation he would 

 for any other "crop. 



February. He should procure, in the month of February, seeds 

 of the AUanthu& rftandulosa. Until he is ready to sow them 

 the seeds are better in the keeping of the seedsman than in his, 

 for they are apt to ferment. Should he find any difficulty in 

 procuring the seed in this country, he can get it from M. Vilmorin, 

 seedsman, Paris, or any other French house. Fellows of this 

 Society can get cuttings from a fine large plant at Chiswick. 



March. He should sew it about the middle or end of March, 

 either in rows or broadcast. 



April and May. The young plants will be above ground about the 

 end of April. As soon as they are capable of being lifted he should 

 plant them out in rows, leaving about a yard between each plant 



July and August. About the middle of July he should apply for 

 a few cocoons to begin his experiment with. These he may procure, 

 either from Lady Dorothy Nevill, Dangstein, Petersfield; or Mr. 

 McGhee, Tynehall, llford, Essex; or Monsieur Andre Marchand^ 

 Eue des Petites Ecuries, No. 50, Paris; or M. Guerin Menerille, 

 secretary to the Society of Acclimatisation, Paris. If he waits 

 until the end of August or beginning of September, he should 

 apply for eggs instead of cocoons. The price charged for cocoons 

 is about 3cZ. each. 



About 10 per cent, of the cocoons will produce moths. These 

 moths should be taken as they come out (every evening will 

 do), and placed in a tray or shallow box with a cloth over it, and 

 so arranged that air may be admitted. 



The females will lay against the sides of these trays (about 350 

 eggs each), and the eggs must be detached either by the nail or 

 a wooden knife Or something of that sort, and laid in a tray with 

 fresh Ailanthus loaves in a room heated to from 70"^ to 80° Fahren- 

 heit, or in the sunshine where they may get this degree of warmth. 

 In like manner, if he receives eggs from others, he should place 

 them in a tray, laying some Ailanthus leaves over them. 



In about ten days the eggs will be hatched, therefore about 

 that time put fresh Ailanthus leaves upon them, so that so soon 

 as they emerge they may have something to feed on. Immediately 

 on the young woftns coming out they will begin to feed on the 

 leaves. After feeding them in the tray for a few days on fresh 

 leaves, he should take them out and transfer them to the plants 

 in the open air.
