NOTES ON PLANT DISEASES OF CONNECTICUT. 731 



page 374, we mentioned this rust as one likely to be brought 

 into this state on imported white pine seedlings from Europe. 

 Its introduction really occurred sooner than was anticipated. 

 Mr. F. A. Metzger first found specimens on a lot of three-year- 

 old seedlings from Germany that had been imported by our 

 State Forester for Mr. C. F. Street, and planted at Wilton. 

 Mr. Metzger, who was employed to set them out, found in the 

 10,000 seedlings from fifty to one hundred that were infected 

 with the rust. He brought specimens to the station the last of 

 April, 1909, but as the writer was in Japan at that time, nothing 

 further was done. 



In the meantime Messrs. Metcalf and Spaulding, of the U. S. 

 Department of Agriculture, who had been looking up infected 

 seedlings in other states, came to this state about the middle 

 of June, and with the forester examined the plantations of the 

 New Haven Water Company at West Haven and the Ansonia 

 Water Company near Ansonia, and found a few very suspicious 

 specimens at these places. Arrangements were made soon after- 

 ward by which Mr. Spaulding and Mr. Graves for the Govern- 

 ment and the botanical department for the station undertook 

 during July to go over the plantations in the state where white 

 pine seedlings had been imported from Europe, and inspect them 

 for this rust, and to destroy any infected seedlings, if found, 

 and any wild gooseberries or currants in their vicinity, as the 

 II and III stages occur on the latter as alternate hosts. It 

 was really then too late in the season to find the fungus on 

 the pines, except far past its prime. However, twenty-four 

 plantations, including about 580,000 seedlings, were inspected, 

 and very suspicious or positively identified infected specimens 

 were found at two additional places; viz., at the Plant estate 

 plantation at East Lyme and at the Groton Water Company 

 plantation at Poquonock. In none of the five places where 

 signs of the pine rust were found were more than a dozen 

 specimens seen, except at the Street plantation, where the dis- 

 eased plants were noticed as they were being set out. A 

 descriptive letter concerning the rust and its reputation was 

 sent to all those who had used imported seedlings. 



In 1910 the botanical and forestry departments of the station 

 undertook to again go over these and other plantations, beginning 

 early in the season, as soon as the rust ordinarily makes its
