3 ft. to 6 ft. 6 in. If peeled, the colour is dirty and the rods 

 poor in quality. Plant 20 in. by 20 in. 



Salix alba var. cardinalis. — The "Belgian Red Willow" is 

 the best working-quality willow that Belgium produces, but is 

 far inferior to the triandra varieties ; it is a heavy cropper, but 

 the shoots rarely exceed 5 ft. 6 in., and they do not make a 

 good colour as white; it finds a ready market with gardeners 

 as green for tie-rods, and is well suited for that purpose. Its 

 great toughness lies in the bark. Plant 18 in. by 18 in. on 

 a damp loam soil. 



Salix hippophaefolia. — This willow is classed as a hybrid 

 of Salix viminalis and Salix triandra by the Rev. E. F. Linton. 

 It is certainly one of the best and hardest-wooded full- 

 top willows grown. Whilst growing, the largest rods 

 have a tendency to throw out side-shoots; but as these 

 are usually of a tender character, they fall away during 

 the winter season or at peeling time. Of all the willows 

 tried on sewage farms, this alone has stood the test 

 of time, and yields a quality equal to many rods produced 

 under ordinary conditions. For all work where a full top is 

 desirable, it is probably unequalled. 



In addition to the above there are other varieties, known 

 in the trade as Violets from the beautiful bloom on the bark 

 (S. daphnoides). White Dutch, Gelsters, Russets, Wigstons, 

 and a few other old-fashioned but good working rods, all of 

 which thrive, without much care, if conditions are suitable to 

 their requirements. 



The experiments which were conducted on the cottage 

 gardens and allotments in 1910, to test the power of resisting 

 Wart Disease believed to exist in cer- 

 Experiments with ta * n var i et ies of potatoes, were renewed 

 Potatoes Resistant in 191 1. The centres selected were 

 to Wart Disease. as follows :— Ravenglass and Carlisle 

 in Cumberland; Rainford and Hay- 

 dock near St. Helens, and Ormskirk in Lancashire; 

 Hooton and Saltney Ferry in Cheshire; Alfreton in 

 Derbyshire; Annesley and Newstead in Nottingham- 

 shire; Hales near Market Drayton, Smethwick, Walsall,
