Polyanthus, The Gold-laced. By R. Dean (Garden, No. 1582.. 

 p. 177, 15/8/1902). — How very difficult it is to raise a really fine variety 

 of the Gold-laced Polyanthus from seed is well known to those who are 

 in the habit of raising seedlings. Although it is possible to raise a 

 thousand seedlings from the best blood, not one may be up to the mark 

 of quality of, say, ' Cheshire Favourite.' The characteristic qualities of 

 the Gold-laced Polyanthus are given, as well as names of some of the 

 best varieties and cultural instructions. — E. T. C. 



Poppy, Harlequin. By. FT W. Oliver (Gard. Chron. No. 797, 

 p. 223, fig. 71 ; 5/4/1902). — A description is given of curiously coloured 

 flowers of a Poppy (Papaver Bhceas) : some were of the usual red colour, 

 some were white, and two were red and white. These flowers were half 

 red and half white. " One outer petal and the adjacent halves of the 

 inner ones were red, the other outer petal with the halves of the inner 

 ones adjacent to it were white." The seeds from these flowers were 

 sown, bat the plants from them all bore red blossoms. — G. S. S,

 An accidental hybrid between P. Bhceas and P. glaucum noticed by 

 M. Claude Monet in his garden. Described as nearer to P. glaucum, 

 and very ornamental. Three varieties have been obtained : P. Moncti 

 genuinum, P. M. hirsutum, and P. M. rhceoides. — C. T. D.

 Coast Of North America. By Henry T. A. Hus (Proc. Cal. Acad. 

 Set. 3rd series, Bot. vol. ii., No. 6, pp. 173-240; 3 plates, 28 figures). — 

 The work here presented was done in the botanical laboratory of the

 follows : — History, morphology, distribution, description of species,

Potato Crop. By O. M. Morris (U.S.A. Exp. Stn. Oklahoma, 

 Hid I. 52 ; December 1901). — This is a small pamphlet on the commercial 

 industry of Potato-growing actively carried on in the valley of the 

 North Canadian River, in Pottawatomie County. 



The soil is sandy and admirably adapted to this crop. The report 

 deals with planting, cultivation, harvesting, yields, and variety tests, &c,
