POTATO TUBER MOTH AND EELWORM. 



Wo now know that this moth and tliis nematode are existent in 

 several parts of our State. AVe know that other sections, often whole 

 counties, are entirely free of them. We know also that both these pests 

 distlgure the tubers and render them unmarketable. 



All of our county horticultural commissioners should use every effort 

 to restrict infestations of both these destroyers to the utmost. If affected 

 potatoes are refused in any locality, they can not be planted, and so the 

 extent of infection will not be increased. All who grow potatoes should 

 be instructed as to the life history of the pests and the appearance of 

 infested tubers, and should be urged with special emphasis not to plant 

 any but sound potatoes. 



I have just received eelworm tubers from a county horticultural com- 

 missioner who says that seventy-five sacks have been shipped to his 

 county. At this planting season the menace from sucli a shipment 

 Mould be great. It would certainly warrant the rejection of the entire 

 lot. — A. J. Cook. 



POTATO COUNTY. 



I have just visited one of our northern counties, El Dorado, which 

 grows a considerable area of very fine potatoes. So far as I know, the 

 vegetables are largely free from blemish or disease. Even scab is very 

 rare. These potatoes are much sought for seed, their reputation being 

 such that they find ready sale at a good profit. Surely, the people of 

 this county are deeply concerned in keeping all these enemies of the 

 potato absolutely out of their county. — A. J. Cook. 



THE WAYSIDE TREES. 



In an article by A. L. Bancroft, Oakland, California, in The Monthly 

 Bulletin No. 10, Vol. II, of the State Commission of Horticulture, 

 entitled "An Improvement in the Setting of Wayside Trees," the author 

 states that he has found an improvement in the placing of roadside 

 trees and thinks his way has never been tried or thought of. 



He says : " In place of rows set the trees in clumps. Let the clumps 

 vary in size and natural groupings to fit the place, from three to thirty 

 in a bunch ; the distance apart of the trees and the number in a clump 

 to depend upon the size and growth. hal)it of the tree, and the distance 

 between the clumps to depend upon the lay of the land, the soil, moisture, 

 exposure and other conditions. The spaces between clumps should be, 

 probably, from fifty to two hundred feet." 



Frank J. Scott, in his book. ' ' Beautiful Homes, ' ' published over thirty 

 years ago, says : " To attempt the varieties of park scenery on an avenue 

 is as much out of place as to compose a park of straight rows of trees." 

 William Saunders, writing on this subject in 1863 says : "In the planting 

 of straight roads and avenues it is essential to preserve regularity of 

 line, as also uniformity in the color and shape of the trees. The nearest 

 approach to the sublime in landscape gardening is in effect produced by 

 extended uniform lines of trees. Continuity of line and uniformity of 

 object, when combined wdth great extension, produce sublimity. Objects 

 are sublime which possess quantity and simplicity in conjunction. To 

 produce this effect it is therefore imperative that only one variety of
