termine the quality of walnuts grown here from the best foreign 

 grafted varieties. For the purpose of these experiments, scion wood 

 from the best varieties g;rown in California and in Italy has been 

 obtained, and a number of the best types of nuts from other foreign 

 sources have been planted. 



The information gained by the enquiry proves beyond doubt the 

 possibility of growing, at least in the southern counties, walnuts pos- 

 sessing the qualities essential to enable them to compare favourably 

 with foreign types, but no one variety has yet been found growing in 

 this country in which all the desired features are combined. The 

 field covered so far has been comparatively limited, and it is now 

 desired to extend the enquiry so as to cover as large a number as 

 possible of the walnut trees growing in this country. 



County Horticultural Officers are cordially invited to co-operate 

 with the Ministry in this extended enquiry by bringing the matter to 

 the notice of all growers of walnut trees. In order that the actual 

 examination of samples may be kept within reasonable limits, growers 

 are asked to submit their nuts to the simple preliminary test indicated 

 in the enclosed memorandum, before forwarding any for critical ex- 

 amination. Further copies of the memorandum and form of report 

 will gladly be supplied to any county officer or to individual growers 

 on application to the Ministry of Agriculture and Fisheries, 10 White- 

 hall Place, London, S. W. 1.
