    1. The first step to make clear the origin of tea, had to be made in North Burma. Where we made a field investigation as to the distribution of wild tea plants and also as to, their way to grow tea manufacture it.
    2. Northe Shan State in Burma, they grow etable tea, called leppet tea, which is found to be grow by minority races in China. It seems moreover that there are doss relations between these plants and those Yunnan in Chira, because the latter plants, have the same qualities about them as the former ones. They grow tea, which they pack in bamboo tube at abut in Kachin state. This is especially interesting in the history of tea.
    3.The same wild tea plants as the Shan-type trees distributed in Kachin state. We see however, many varieties of the tea plants. Their leaves measure 14 cm in length, 8 cm in dia-meter, a tall tree and have sometimes no hair.
    4.I am led to belive, that by their improved skill in growing tea and also in manufacturing process, they will some day be able to make, their country an exporter.

    This is a study on the effects of plastics used for graftings. This report deals with a simple examination of the various aspects of grafting unions of rootless stocks, and with its applications like grafting-cuttings of rosaceous trees, as a new agricultural experiment. This is a discovery second to the report on the leaf-removal and longtime storage of grafting scions by S. MIKI. The previous report was made in 1) and explained the longtime storage of scions and its perfect results. Through soft plastic film packing the storage method has provod successful.
    1. According to this simple inspection method of grafting unions, examination may be con-ducted throughout the year. Naturally wintertime storage is feasible then, and grafting union is sure if the grafting are preserved till warm springtime. Thus winter grafting may become a good side-job for farmers in their wintry slack season.
    2. The sole difficulty in this storage method is the growth of mold and eventual decay of the materials just as in case of scion storage. Lower temperature invites less mold.
    3. As for grafting-cutting to which this method may be applied most effectively, so for as the stocks are usable for cuttings, good results will be gained on the nine fruit trees and many other trees.
    4. The combination of scion and stock in grafting-cuttings must be normal/revrse, which has been verified as the best combination in many experiments. This can be a quicker way of conducting examination only.
    5. This method can be adopted indoor working of rooted stocks as well as of rootlese stocks.

    1. Three setting periods, April 15, May 1 and May 15 had been tried.
    In each period, when planted, plants were protected with polyethylen mulching and tunnelcovering.
    Under this condition, plant growth was investigated.
    2. This investigation was resulted in the following; April 15 and May 1 plots protected with mulching and tunnel-covering showed the best growth.
    And it was proved that earlier planting protected with those film shelters brought a big effort comparing plants not protected with those materials.
    This test showed that the best planting period of plants protected with plastic mulching and covering was the period, April 15 to May 1.
    In case non-shelters, adquate plant-set priori will be in some time after May 15.
    3. The more the growth is accelerated the earlier the flowers bloom and the flowers bloomed in late July became unripe fruits when harvested.
    4. Earlier growth and flowering brought higher yield and the plants in the protected plots produced good yield though carrying the normal growth.
    Those mulching and tunnel covering took a big effort in keeping off the weeds.
