JOURNAL OP HORTICULTURE AND COTTAGE GARDENER. 



[ October 11, 1877. 



reply to this ie, I have grown Potatotes on the same land for 

 seven years and had no disease. I have tried all sorts of 

 manure, and I find that with a good dressing of quick or gas 

 lime Potatoes can be grown in the same land for a number of 

 years. As for diseased Potatoes having anything to do with 

 the next planting is out of question. Dress your land well in 

 December or January with quick or gas lime, and you will 

 have no disease. If anyone Bhould have a doubt let them try 

 one pole of ground with 2 cwt. of lime, and I shall be most 

 happy to hear the result. — W. G. 



of charming flowers. Mr. Douglas grows this Primula well, 

 and finds it worthy of his best care. Its cultivation is gradu- 

 ally increasing, as one of the most distinct and pleasing oi 

 the attractive family to which it belongs. 



PRIMULA VILLOSA NIVEA. 

 Some confusion appears to exist as to the correct name of 

 the charming Primula now figured. It is popularly called 

 Primula nivalis, and is referred to under this name by Mr. 



THE CLOUDED YELLOW BUTTERFLY 



(COLIAS EDUSA.) 



It is curiously illustrative of popular caprice that while the 

 Colorado beetle, which has not yet settled here, has been 

 puffed into astonishing notoriety by newspapers and peri- 

 odicals, many interesting facts which immediately ^concern 

 British entomology receive no mention. I have seen hardly 

 any references beyond scientific journals to the abundance ia 

 which Colias Edusa has appeared in 1877, there being the 

 unprecedented circumstance of a numerous flight of J, these

Donn; the Dahurian P. nivalis has, however, purple flowers. 

 It is known also as P. nivea (the Snowy Primula), and the 

 name is appropriate, for the flowers of no Primula are more 

 pure and chaste. The author of the " Botanical Magazine " 

 considers it a variety of P. villosa on account of its essential 

 resemblance to that species — its villous wedge-shaped leaves, 

 toothed at the upper ovate part only and quite entire below, 

 and by the funnel-shaped form of its flowers. It is one of the 

 most attractive of small-growing Primulas, and when grown 

 in pots or pans, and flowered under glass, as it should be, few 

 dwarf plants during early spring are more noticeable in the 

 greenhouse. It requires much the same cultural treatment as 

 the Auricula, and at this period of the year requires attention to 

 prevent it from damping ; indeed nearly all the dwarf Primulas 

 demand a little extra care now by providing them with suitable 

 winter quarters. A shelf in a light well- ventilated house or 

 the wooden stage of a cold frame are suitable for this tribe of 

 plants during the winter months. When they show signs of 

 growth in the spring a top-dressing of fresh enriched soil and 

 more copious supplies of water aid in producing good trusses 



butterflies in the spring as well as an autumn brood. Indeed, 

 in some places they almost outnumbered the common Whites. 

 Formerly scarce and then seemingly partial to the coast, 

 C. Edusa has gradually become commoner, but this season 

 has brought it out in unusual force ; and as it feeds in the larva 

 Btate on Clover and Lucerne, it might furnish a topic for 

 alarmist paragraphs. There is, however, a probability that 

 our very variable winters will always keep the species in some 

 check.— J. R. S. C.

TREGOTHNAN, THE SEAT OF VISCOUNT FALMOUTH.— No. 2. 



The mansion, a massive pile, was figured last week. The 

 walk (fig. 57) leads from the lawn and forms a singularly 

 appropriate approaoh to the house, passing as it does among 

 lofty trees, fringed with a fine growth of Rhododendrons, a 

 magnificent old Silver Fir standing out prominently, meeting 

 the eye agreeably without obstructing the view. At the end of 

 this walk, close by the house, are many Camellias wonderfully
