trical avenues also. Eggs of some of tliese valuable races can 

 be obtained at tbe proper season and sent by Post in a Quill. 

 The imported Japanese Eggs are sold by weight just as they 

 arrive, December to May, and range about 6 grains, Troy Is, 

 20 grains 2s 6d, 40 grains 43, 150 grains 10s, 3G0 grains 20s. 

 These however having undergone a long voyage, it would 

 scarcely, I think, be advisable to risk them for another voyage, 

 therefore the Picked Fertilised Eggs English and Austrian 

 acclimatised are tbe best aud safest and are procurable from 

 September to May ; the prices are necessarily higher, vizt : 

 per 5 Is, 35 5s, 80 lOs. The Austrian and Hungarian Eggs 

 are reckoned the best ; the chief breeder is Le Baron le Breton 

 (a Eranco-Austrian) who for the last five years has uparal- 

 lelled success in rearing particularly this valuable Silkworm 

 (Yama-Mai), and in 1869 set aside 27,000 Cocoons in order 

 to obtain a large stock of accUmafised Eggs, Avhich are cheap- 

 est in the long run, being far more certain and likewise 

 healthier than Eggs direct from Japan or China. The English 

 Eggs of B. Mori, feeding on the Morus alba are Is a 100, and 

 Is 6d a 1000 ; the ijtiported Japanese Eggs best varieties on 

 Card are Is 6d per square inch. Australian Eggs arrived here 

 in the spring and vary according to the supply and demand. 

 There are also several other kinds of Worm of whicli Eggs 

 may be had, such as the Ailanthus Silkworm (Boinlnjx Cynthia) 

 which clothes the greater part of North China. I have spe- 

 cimeus of this Worm and its Silk given to me by my friend 

 Dr. Gueriu Menneville, in Paris, who has done so much for 

 Sericiculture in France. It has partially been tried here 

 on a small scale as the Ailanthus tree is perfectly hardy 

 and stands storms and sea breezes well, wbich few trees do, 

 but the Silk had two great faults with the manufacturers ; so 

 my friend Professor Simmonds told me, that is, its very dark 

 colour which can only take dark colours, and its extreme brit- 

 tleness, w^hich prevented' it been reeled off like other Silks, 

 and required a special machine to be manufactured for the 

 purpose, which now achieves the object. The Ailanthus 

 fjlandidosa is a very ornamental tree with beautiful pin- 

 nated foliage reminding me of the beautiful Cicca disticcha 

 in Mauritius. Then there is tlie Actias Luna, pretty as its
