The effect of the fungus is to distort or kill shoots developing 

 in May or June. In case they are not killed before autumn the 

 immature wood is often caught by the frost. Nursery experi- 

 ments, using lime-sulfur spray and powdered sulfur to control 

 the disease, resulted in the recommendation of one or two appli- 

 cations of the former in strengths of 1 130 of the so-called normal 

 solution. The remedial effect was very striking, as evidenced by 

 the healthy matured shoots of the sprayed plants. Since conidia 

 do not live over winter it is of no use to burn leaves and detritus.

Carl Bannwart, Secretary of the Newark 



Protection Shade Tree Commission, New Jersey, pre- 



of sents a timely and popular, yet forcible, plea 



Shade for the better protection of our shade trees 



Trees. against the evils of the curbstone which 



he considers their greatest enemy. He 



states quite aptly that "the present day curb descends from a 



barbaric age when everything was sacrificed to compactness." 



As a remedy for the difficulty, in order to conduct sufficient 

 water to the tree roots, he recommends several devices, the key- 

 note of which is a grating, either in the curb or in the sidewalk, 

 or even between the trees, within which is an area of cracked 

 stone to catch water from rains or street flushings. The author 

 illustrates his ideas by drawings. Washington, D. C. is cited as 

 a city in which the engineers consider the needs of the trees. The 

 attempts of the Massachusetts and New Jersey officials to ac- 

 complish the same end are briefly outlined.

Prof. Decoppet from the Swiss Experiment

structive in forest nurseries. 

 The experiments carried on since 1904, mainly with carbon- 

 bisulphide lead to the following conclusions : Not only are insects 

 in part killed but the fertility of the nursery is increased, whereby
