368 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. 
Gardening (published by John Lane, 1903). It is full of useful 
information from cover to cover. The chapters on How to form a 
Collection, Certificated and other fine varieties, as well as those on 
cultivation, are particularly good. The photographic illustrations 
are excellent. 
Then Mr. Jacob has written the Daffodil volume of The Present- 
day Gardening Series.* It is a brightly written book, full of interesting 
chapters, such as The Daffodil in Books, History, Raising new Varieties, 
The R.H.S. Classification, Lists for different purposes, and a Calendar 
of Operations. The eight coloured plates in this volume are, I think, 
the best in any of this well-illustrated series of books. 
The fullest account of the Snowdrops is to be found in a mono- 
graphic sketch of the genus Galanthus, by Dr. Gunther Ritter Beck 
v. Mannagetta, in the Ittustrirte Garten- Zeitung* February 1894, 
Vienna ; but unfortunately it is unobtainable and also in German. 
It is a careful piece of work and brings together a mass of references. 
In English the best is Burbidge's paper read before the Royal 
Horticultural Society, March 10, 1891, and published in vol. xiii. 
part ii. of the Journal. He gives a capital alphabetical list of the 
then known varieties. The late Mr. Allen's and Mr. Melville's 
papers in the same volume also provide useful facts. 
The Clematis is the subject of five works, three of which call for 
notice. The oldest is " The Clematis as a Garden Flower," * by 
Thomas Moore and George Jackman, published at the Woking 
Nursery, 1872, and a new and revised edition in 1877, with two coloured 
and fifteen black-and-white plates, many of which are by W. G. Smith. 
It is a trifle old-fashioned by now, both in style of illustration and 
subject-matter, but the descriptive notes on species and varieties are 
still very useful. A new and up-to-date edition with photographs 
of all the varieties would make a good book. 
Of course, a great deal is said about the beauty and uses of Clematis 
Jackmannii, and rightly so, for it is not easy to overpraise this grand 
plant. It is interesting to notice that the author declares it to be a 
seedling, the female parent being a Viticella type. 
The next writer, M. Alphonse Lavallee, declares this plant is 
none other than a Japanese species, C. hakonensis, and much has 
been written on these different views. Anyway, " Les Clematites a 
grandes fleurs"* is a good book. Its title tells us it is a "De- 
scription et Iconographie des especes cultivees dans l'Arboretum de 
Segrez." It was published in Paris in 1884 as a 4*0, and contains 
twenty-four beautiful plates drawn from life and lithographed by 
Mile. Bergeron. 
There are charming reproductions of very clever pencil drawings. 
It is difficult to make an artistic plate out of one flower 6 inches across 
on a quarto page, and these drawings are worth studying by anyone 
anxious to succeed in this line. The smaller -flowered forms are 
beautifully treated, especially in the foreshortening of the fully shaded 
flowers and the delicacy of outline of the more lightly treated leaves.
