THE AIM OF the; station. Every citizen of Maine concerned in agriculture has the right to apply to the Station for any assistance that comes within its province. It is the wish of the Trustees and Station Council that the Station be as widely useful as its resources will permit. In addition to its work of investigation, the Station is -pre- pared to make chemical analyses of fertilizers, feeding stuffs, dairy products and other agricultural materials ; to test seeds and creamery glassware; to identify grasses, weeds, injurious fungi and insects, etc. ; and to give information on agricultural matters of interest and advantage to the citizens of the State. All work proper to the Experiment Station and of public benefit will be done without charge. Work for the private use of individuals is charged for at the actual cost to the Station. The Station offers to do this work only as a matter of accommo- dation. Under no condition will the Station undertake analyses, the results of which cannot be published, if they prove of gen- eral interest. CORRESPONDENCE. As far as practicable, letters are answered the day they are received. Letters sent to individual officers are liable to remain unanswered, in case the officer addressed is absent. All com- munications, should, therefore, be addressed to the Director or to the Agricultural Experiment Station, Orono, Maine. The post-office, railroad station, freight, express and telegraph address is Orono, Maine. Visitors to the Station can take the electric cars at Bangor and Old Town. The Station is connected by telephone. ( HISTORICAL NOTES FOR 1909. HiGHMOOR Farm. The Legislature of 1909 appropriated $10,000 for the pur- chase of a farm on which the Maine AgricuUural Experiment Station shall conduct experiments in orcharding and with corn and other farm crops. The committee on selection have decided upon Highmoor Farm situated in the counties of Ken- nebec and Androscoggin, and largely in the town of Monmouth, The farm consists of 225 acres, about 200 of which are in orchards, fields and pastures. There are in the neighborhood of 4,cco apple trees upon the place which have been set from 10 to 20 3'ears. The fields that are not in orchard are well adapted to experiments with corn, potatoes and similar general farm crops. The house is two-storied with a large wing and contains about 15 rooms and is well arranged for Experiment Station offices and the home of the farm superintendent. The barn is large ; arranged for 32 head of cattle and 6 horses. The buildings are supplied with running water from a never failing spring situated on the farm. The Farmington branch of the iMaine Central Railroad bounds the farm on the west and it is expected that a flag station will be made at the farm. The farm is purchased in the name of the State but by law "the Director of the Maine Agricultural Experiment Station shall have the general management, supervision and control of the said farm and of all investigations thereon." The property was acquired so late in the season that no inves- tigational work could be undertaken in 1909. It is planned to begin another season studies upon orchard management, corn and oat breeding and potato culture. The farm will be used not merely for practical field experiments in horticulture and agri- culture but also for studies of practical problems by the ento- mologists, plant pathologists and biologists of the Station. viii MAINE AGRICULTURAL EXPERIMENT STATION. I909. Publications. The Station is organized so that the work of investigation is distinct from the work of inspection. The results of investi- gation are published in the bulletins of the Station. These make up the annual report for the year. The results of the work of inspection are printed in publications known as Official Inspections. These are paged independently of the bulletins and are bound in with the annual report as an appendix thereto'. Miscellaneous publications consisting of newspaper notices of bulletins, newspaper bulletins and circulars which are not paged consecutively and are not included in the annual report are issued during each year. All of the bulletins issued by the Station are sent to the names upon the official mailing list prepared by the Office of Experi- ment Stations, to all newspapers in Maine and to libraries and to agricultural exchanges. Bulletins which have to do with general agriculture and the Official Inspections which bear upon the feeding stuffs, fertilizer and seed inspections are sent to a general mailing list composed chiefly of farmers within the State. The publications having to dO' with the food and drug inspection are sent to a special list including all dealers in Maine and other citizens who request them. The annual report is sent to directors of experiment stations and to libraries. Copies of all publications are sent to the newspapers within the State and to the press on the exchange list outside of the State. BULLETINS PUBLISHED IN I909. No. 164.
