Book excerpt: Excerpt from Report of the Botanist for Years 1917-18 Infected seedlings before the I stage appears in the spring are usually detected by their bunched leaves and soft swollen stems. When the fruiting pustules appear they are quite conspicuous and the disease is easily recognized. After these disappear in late June, there remains only the roughened dead bark or a yellowish-green area of invaded smooth bark which will break out the next year, to indicate infection. Once the cambium is killed all around the stem the parts above die. Very young infected seedlings do well to live a year, but those two or three years old may live for several years. On older trees if the infec tion is at the: ends of the twigs the damage is not serious, but once the main trunk becomes invaded the tree is doomed though it may re main in Vigorous growth for several years and seem perfectly healthy on casual examination of the foliage. Elimination of Ribes in the vicinity of seed beds, thorough Spraying of the beds with Bordeaux after midsummer if grown in an infected region, use of uninfected seedlings only for planting, inspection of plantations from foreign stock for infected pines, destruction of all wild or cultivated Ribes in plantations and for 300 yards around the same, are precaution ary measures advocated for this state.430 connecticut experiment station bulletin 214. Upon positive identification, the botanical and forestry depart ments, in co-operation with the U. S. Department of Agriculture, inspected during 1909 most of the larger plantations scattered over the state, with the result that the blister rust was found in small amounts in several of them. All of the infected trees found were destroyed. In 1910 most of these plantations were re-inspected and several smaller ones were inspected for the first time. About out of the imported trees that had been set out, were thus inspected once or twice during the two years. As no trees were found infected in 1910, the inspection was practically discontinued. An account of this work appears in the botanist's report for 1909-10. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
