No. 2 "ANGLER' FEBRUARY, 1941 EDITORIAL Having finished 1940 with a production record of which we are really and truly proud, we ap proach the 1941 season in the spirit of marked enthusiasm. The holding ponds at our hatcheries are loaded with large fish in readiness for the pre-season stocking program scheduled to get underway in March. Nothing but fine takable Brook, Rainbow and Brown Trout will be placed in the ap proved streams open to public fishing. Approximately 1,200,000 trout alone, are waiting for the dis patch orders which will send them out over the State and into the creeks and streams. Most gratifying indeed, has been our production of black bass which was actually doubled in 1940. Withstanding a most peculiar season last year, we succeeded in producing more than a half million bass and the result of this accomplishment is certain to have a telling effect during the season this year. This is true of all the warm water species and in accordance with the policy of the Board, we are developing larger sizes, to the end that eventually most of the fish stocked will be of legal size and over when placed in the stream. This policy may serve to reduce the numbers heretofore planted but will overwhelmingly offset them in size and weight thus assuring utmost satisfaction to the fishermen. Our program of expansion is rapidly creating new ponds and facilities at the hatcheries. WPA Projects are busily engaged in this program which when completed will certainly challenge any thing of its kind in the United States. I invite you to visit and observe these fish farms and see for yourself just how your enterprise is advancing. The main points where this expansion can be best observed are at Pleasant Gap, Centre County; Corry, Erie County; Huntsdale, Cumberland County; Pleasant Mount, Wayne County and the Pymatuning Sanctuary in Crawford County. I as sure you that you are welcome and the men in charge are ever ready to make your visit a pleasant and informative one. This year for the first time in the history of the Department, we will stock bass in lakes hav ing an area of forty acres or more which are now inhabited with these fish and have been approved in accordance with our survey just recently concluded. In addition to these lakes, several water companies have granted us permission to use their reservoirs. In these bodies of water, the Board will establish fish nurseries which we believe will be productive of exceptionally good results with no direct expense, save the cost of the season's harvest. An outstanding accomplishment during the past year has been the introduction of brand new and quite successful departures in the culture of fish. Among these has been our newly devised suspension basket adopted in connection with the culture of black bass and other warm water fish; thus developing dual purpose ponds. Of special interest also, is the progress made in the line-breeding of fish. This venture alone offers a strong bid to revolutionize present-day production of large, well colored, healthy fish by cutting in half the time required heretofore in developing fish to the sizes I know you are all interested in having planted for your entertainment and sport. We are now equipped with most modern refrigerated food-storage plants at both Pleasant Gap and Huntsdale, permitting the Board to hold tons of food and affecting a tremendous saving to the sportsmen. Some idea of this problem can be gathered from the fact that the fish at our hatcheries consume more than 1,000 tons of food each year. Yes, the work and program of your Board of Fish Commissioners, timed to meet the present- day demands of all year fishing, is swiftly marching on. Keeping abreast of ever changing condi tions with a judicial administration of the affairs of the State's fishermen. I am indeed elated with the prospects for the 1941 season bearing down on us. I say that we are ready and equipped to meet it and with the cooperation of a kindly weather-man who may spare us the ravages of extreme deluge and drought, everything points to a very fine fishing season.

Preparing a genatalic slide NOTE is quite a task, especially for amateurs; in fact when it becomes necessary to resort to nt it, the insect should be sent to some authority 9| for verification. Many insects can be readily to and accurately determined from the location and arrangement of the wing veins; lengths of the various parts of the legs and other characteristics. Naturally one must have a monograph on the order, and by closely studying and following the keys, the amateur can finally trace it down to the specific name. A good glass is absolutely essential. I have to a Bausch Lomb, No. 14 X, Hastings Triplet; bl the diameter is smaller than a dime, yet it bt is remarkably powerful, and will bring out bl the necessary details in following the keys.

One naturally must know and recognize du the principal veins, the Costa, "C"; the Sub- M; costa, "Sc"; the Radius, "R"; the Media, "M"; 3b the Cubitus, "Cu". and the Anal veins "A". In general it is a complicated and fascinating study, and the field is so large that one should not dabble in various orders, but should con fine his activities to one group; and in that one group, one should get every monograph and all the available literature on the subject.
