non-flowering and unattractive sorts. Judicious thinning' of the trees 

 under the direction of an expert was extended over a large part of the 

 reservation, the brush and smaller wood was burned, and the larger wood 

 sold after creosoting all nests upon it. This work has of itself made a 

 great improvement in the forestation of the reservation and in its avail- 

 ability as a place of resort for the public, and has materially reduced 

 the number of trees necessary to be cared for. The creosoting of the 

 nests was carried on with great fidelity wherever there were pines and 

 hemlocks, and along the roadsides and over a strip from 200 to 500 

 feet wide along the borders. This work proved very effective. Less 

 thorough creosoting was extended over nearly all the rest of the reser- 

 vation. Subsequently the trees over most of the reservation were banded 

 with Tanglefoot, and the caterpillars below the bands destroyed as 

 thoroughly as the available money would permit. Later conifers and 

 the trees along the roadside and the areas which seemed most likely to 

 be defoliated were sprayed. Winrows of oiled hay were vised for pro- 

 tection against the spread of the caterpillars in the most seriously in- 

 fested sections. A considerable balance of the appropriations was for 

 the first time kept for work in the autumn. 



As a result, the permanent thinning and forestry work of the reserva- 

 tion was advanced almost to completion; no conifers were defoliated, 

 the borders remained quite free from defoliation, practically no infesta- 

 tion went from the reservation out upon other lands or was allowed to 

 come from without into the reservation, and infestation was thoroughly 

 controlled in large areas and greatly checked throughout the reserva- 

 tion. Certain adverse circumstances limited the effectiveness of the 

 work. It was so enormous that with no large appropriations available 

 until February it could not get under way nor be carried on with com- 

 plete efficiency. The Tanglefoot for banding could not be obtained in 

 proper shape at an early date. The unusually dry weather of last 

 spring made it possible for the caterpillars to spin a web over the 

 Tanglefoot band and so cross to the foliage to a greater extent than 

 ever was known before, a condition against which the limited number 

 of men employed, under the appropriation then available, were power- 

 less. In spite of these adverse conditions, however, no trees were killed 

 and a great advance was made in the effectiveness of the work. 



The balance saved for autumn and early winter work has made it 

 possible to advance further toward complete work than in any previous 

 year. It now seems possible to extend throughout the reservations the 

 thorough work of creosoting which placed the pests under complete 

 check in the sections in which it could be similarly employed last year. 

 If the work can be continued with the same completeness throughout the 

 reservations, it is believed that next summer will show entirely satisfac- 

 tory results and a marked decrease in the expense for the ensuing year. 

 If it is not so continued, the work will fall back again to its former con-
