• Laboratory Performance of Wicking Fabric H2Ri in Silty Gravel, Sand and Organic Silt

      Connor, Billy; Zhang, Xiong (16-05)
      The use of wicking fabric, H2Ri, is growing in its use to remove water from roadway and airport embankments. Past research has shown H2Ri to be effective in sands and fine grained materials in roadways up to 32 feet in width. However, there is a desire to use H2Ri for airports which require a minimum width of 75 ft. This project tested H2Ri in a 73-foot flume in a crushed surface course with 14 % fines. In addition, the fabric was tested in a 22-foot flume with a sand and with an organic clay. The intent was to bracket the material for which the H2Ri will work. The study showed that the fabric will easily move water 73 feet in a silty gravel. The study showed that the fabric was also able to readily remove water in sand. However, the fabric blinded when used in organic silt and proved ineffective. The study also showed that using simple overlap of the H2Ri as a splice, while effective, was not as efficient at moving water as the fabric itself. Consequently, moisture tended to build up around the splice.

    • Suggestions to Pioneer Farmers in Alaska

      Georgeson, C. C. (Government Printing Office, Washington, D.C., 1902)
      A study of the agricultural resources and capabilities of Alaska was begun under authority of Congress in 1898. Results of the earlier preliminary surveys seemed to justify the continuation and extension of the work and its establishment on a more definite and permanent basis. This has been carried out by the organization of a system of stations for observation and experiment at different points in the Territory which seem best adapted to the purposes in view. Stations have now been established at Sitka (the headquarters), Kenai, and Rampart on the Yukon. Five reports giving the results of the agricultural investigations in Alaska have been issued as Congressional documents and bulletins of the Office of Experiment Stations, U. S. Department of Agriculture. Those who have received these reports and who have noted the letters which are published in them from settlers in nearly all parts of the territory south of the Arctic Circle can doubt no longer that Alaska has agricultural possibilities. These letters bear testimony that hardy vegetables have been grown with marked success almost everywhere in Alaska where they have been tried, and that, likewise, early maturing grains have been grown successfully in many places (Pls. I and II). Potatoes, cauliflower, cabbage, kale, peas, lettuce, turnips, ruta-bagas, and radishes have been grown at nearly every white settlement in the coast region and in many places in the interior (Pls. Ill and IV). Early maturing varieties of barley, oats, and spring wheat have yielded well at Dawson, in the Yukon territory, and at Eagle, Alaska, near the Canadian boundary. At Rampart, on the sixty-fifth parallel, a station was established by the Department of Agriculture in the summer of 1900. Winter rye seeded there in August of that year lived through the winter under a good covering of snow; although the temperature fell to 70 degrees below zero, it came out in the spring in perfect condition and matured grain by the 1st of August, 1901. Barley seeded at this station in May was ripe by the middle of August. At the headquarters station, at Sitka, spring wheat has matured with good results for three years past, and barley and oats have been grown there for four years. These grains have likewise been grown successfully at the experiment station at Kenai, on Kenai Peninsula. Barley, oats, and wheat have prospered well at Copper Center, in the Copper River country, and oats have been grown to maturity on Steele Creek, a tributary of the Fortymile, in latitude 64°. Oats and barley have been matured at Skagway; Killisnoo, on the coast, and at Selkirk, on the Upper Yukon. The reports referred to give data from many other parts of the Territory which are proof that it is possible to farm successfully in Alaska if one understands the conditions and proceeds in his methods of work in accordance with the teachings of experience in Alaska. The pioneer who comes to Alaska to farm often finds that it is not safe to follow the customs with which he is familiar in regions farther south. The season is shorter than it is in the States and he must, in order to insure success, select early maturing varieties of both vegetables and grains. In the coast region the climate is wet and the soil is often water-logged, making drainage necessary in many places; Again, the pioneer soon learns that new soil, which contains more or less vegetable matter, does not yield satisfactory crops until it has been cultivated for two or three years. When he sows good seed on what appears to be rich soil, and the crop makes only an indifferent growth, he is apt to blame the climate for the result, when, as a matter of fact, the partial failure is due, in most cases, to the condition of the soil and not to the climate. These peculiarities in Alaska should be well understood at the outset, and it is chiefly to point out the causes of failure to those who have had little or no experience in Alaska, and to call attention to practical methods of doing the work, that these suggestions are offered.
    • Vegetable growing in Alaska

      Georgeson, C. C. (Government Printing Office, Washington, D.C., 1905)
      In this bulletin an attempt is made to present in an assimilated form what experiments and experience have taught as the best practice for vegetable growing in Alaska. It is of course understood that it is utterly impossible to give directions which can be followed in all places and under all circumstances. The Territory of Alaska is so extensive and the climatic conditions so variable that a practice which may be highly satisfactory in one section or in a given locality may result in total failure in others. Indeed, it is not infrequently the case that a practice which is successful in any given locality one year may result in failure the next year. This is the case, for instance, when the season is very wet one year and dry the next. In a wet season it is quite often desirable to raise the seed beds 4 to 6 inches by shoveling out the paths between them, but this practice is not a success in a dry season. It is therefore possible to give only general directions in a bulletin which is intended to be of use in the whole Territory. There are two factors which modify the practice in Alaska as compared with farming and gardening elsewhere; and these are (1) the climate, and (2) the soil. The Alaska climate has a reputation for rigor and inclemency on which it is not necessary to comment here. This fact is accepted as a matter of course. The fact that the soil differs in many respects from soil in more temperate latitudes is perhaps not so well understood. Such is, nevertheless, the case, and before one can work it successfully he must learn, either from his own experience or the experience of others, in what respects it differs from soil in lower latitudes.
    • Haymaking at Kenai Experiment Station

      Ross, P. H. (Government Printing Office, Washington, D.C., 1907)
      During the haymaking season the weather along the Alaskan coast is generally so unfavorable, with prolonged intervals of rain, a sun whose beams are daily growing weaker, and shortening hours of work, that the statement has often been made that the curing of hay in Alaska is impossible. A study of the weather record seems to confirm this statement. There are three conditions, however, applicable to the Cook Inlet region (and it is believed the first two at least will apply to the whole coast region) that tend to simplify the task of hay curing. First. The manner of precipitation. The rains are never dashing, but fall for the most part in a gentle drizzle. Owing to this, an ordinary cock of hay will withstand a long siege of rainy weather without becoming wet except for a distance of 3 or 4 inches from the surface. Second. The low temperature, which allows green or damp hay to remain in the cock for several days without heating or molding. Third. The southwest winds. The winds are always dry, of high velocity, and blow continuously night and day for three or four days at a time, thereby preventing dew and frost. These winds are more effective than the sun as a drying agent at this time of year. As a clear sky is almost without exception contemporary with a southwest blow, the value of these winds in haying time can be appreciated. Since the inauguration of the work at this station in 1899 the stock belonging to the station have been fed nothing but native feed. This has consisted almost exclusively of hay, and enough of it has always been cured to winter the stock comfortably. During the last two years the station has had about 25 acres under cultivation, and the bulk of this has been given over to growing grain hay. Special attention has been paid to hay curing during this time, and the following notes and deductions therefrom are written in the belief that they will be of practical value to the Alaska pioneer.
    • Information for Prospective Settlers in Alaska

      Georgeson, C.C. (Alaska Agricultural Experiment Stations, 1916)
      This circular is designed to give prospective settlers in Alaska, and particularly homesteaders, information on subjects which will be of more or less vital interest to them. It is designed also to call their attention to many factors in the situation on which they should be informed before settling in a new and comparatively little-known territory.

    • Production of improved hardy strawberries for Alaska

      Georgeson, C. C. (Government Printing Office, Washington, D.C., 1923-10)
      Alaska is a vast country of very diverse physiographic configuration, lying between latitudes 54° 40' and 71° 20' N. and longitudes 130° W. and 172° E., and covering an area of 580,000 square miles. It has two climatic belts, that skirting the Pacific Ocean along the coast region, and that of the interior. The climatic differences in these two belts are due to the grouping of mountain ranges. In the coast region the winters are comparatively mild, the summers are cool, the temperature ranging between 50° and 70° F., and in some places rising to 80° F., and the precipitation, averaging from 40 to 160 inches a year in different places, is conducive to a luxuriant vegetation. Southeastern Alaska, which is an extension of the coast range, is a rough, mountainous section valued for its minerals and its timber. There are only few areas of real farming land in this section, but there are, nevertheless, small tracts of land in valleys, bays, coves, and inlets which are suitable for farming on a small scale and especially for gardening. In the interior, a vast area lying north of the Coast Range Mountains, the winters are severe, the temperature occasionally falling to 65° below zero, the summers are short and uncomfortably warm, the temperature at Rampart frequently reaching 96° F., and the rainfall (including melted snow) is light, averaging between 9 inches in the Copper River Valley and 14 inches in the Tanana Valley in normal years. The growth of vegetation in the interior is not so luxuriant, but more nearly approaches that of the normal in the States. In the interior are many valleys which again differ from each other in climatic conditions. Such are the conditions that confront farmers and gardeners in Alaska. The common tree fruits, such as the apple, pear, plum, and cherry, have not as yet given much promise of success. Doubtless in time there will be developed by hybridization varieties which will be adapted to these climatic peculiarities. In favorable years some apples and cherries reach maturity, but ordinarily the summers in the coast region are not warm enough to mature these fruits. In the interior the summers are not long enough to mature fruits, and the trees freeze down to the snow line in winter. Although Alaska is not as yet adapted to fruit growing in a general way, it is adapted to small fruit growing—that is, to bush fruits. Red currants and raspberries are indigenous in Alaska and grow wild in abundance up to and beyond the Arctic Circle.
    • Eradication of tuberculosis in cattle at the Kodiak Experiment Station

      Georgeson, C. C.; White, W. T. (Government Printing Office, Washington, D. C., 1924-01)
      Southwestern Alaska is eminently fitted for cattle raising, particularly Kodiak Island, where nutritious grasses grow in abundance and there is little timber, the vegetation being mainly bushes, grasses, and other low-growing plants. This region, including the several other islands lying off the mainland, has a moist climate accompanied by no great variations in temperature, the thermometer in summer seldom registering as high as 75° F. and in winter rarely reaching zero. The shore skirting Kodiak Island is cut by numerous deep bays, at the heads of which lies most of the tillable land. The remainder of the island is mountainous, the land gradually rising from near the seashore to a height of 1,000 to 3,000 feet. Kodiak Island was chosen in 1907 as the location for a cattle-breeding station to determine the adaptability of cattle to the climatic conditions prevailing there.

    • Cereal growing in Alaska

      Georgeson, C. C.; Gasser, G. W. (Government Printing Office, Washington, D. C., 1926-05)
      Prior to the establishment of the Alaska Agricultural Experiment Stations it was almost universally believed that Alaska was a frozen, inhospitable wilderness, and therefore worthless for agricultural purposes. Even as late as 1899 it was declared wholly unreasonable to expect anything like cereals to grow so far north, this statement being fortified by an account of the glaciers and ice fields that the tourist sees in the coast region. To-day, however, public opinion is favorably changing as the result of experiments carried on by the stations; and it is beginning to be realized that the country has great agricultural possibilities, its productive power being merely a matter of development.
