    Jean-Jacques Rousseau et Ermenonville
    En France également, it ne reste que peu de jardins paysagers bien que leur histoire soit relativement récente. Pour l'auteur, une des raisons de cette rareté est le fait que les jardins paysagers changent facilement avec le temps, surtout si on ne les soigne pas avec assiduité.
    Actuellement, it est encore possible de se rendre compte de l'aspect d'un jardin paysager au Petit Trianon, au Parc Monceau et dans quelques autres jardins. Mais c'est le Parc d'Ermenonville qu'il faut considérer comme le meilleur jardin paysager de l'époque préron ant que en France.
    Le Parc d'Ermenonville a été créé par le marquis René de Girardin d'aprés les idées de Jean-Jacques Rousseau qui était un admirateur passionné de la nature et qui vécut en ce lieu les six derniéres semaines de sa vie. Etant le seul jardin où les idées de la Nouvelle Héloïse ont été ralisées, le nom d'Ermenonville est inséparablement lié à celui de Jean-Jacques Rousseau.

    The word ‘Kohan’ is mentioned in the “Sakuteiki” five times. Hitherto, on its meaming, two different interpretations are put, namely-‘Goban’ (A checkerboard), and ‘kowan’-that means ‘request’. But I found that they are both mistaken and that formerly it meant ‘a quarter’. This is the very word, if applied to the referred passages. In the next place, according to my study of the block letters and the contents of the sentences, I found that ‘koi’ was the misreading of Chinee letter ‘iro’.

    This report is a study on defoliaton in the different landscape trees.
    The times when the leaves begin to fall and they are all gone off the trees, and these defoliaton periads were respectively measured in the trees of 250 species.
    The progresses of becaming leafless in the trees of 200 Species were analysed by the diagram
    The leaves began to fall at the end of September to the beginnig of octorber, and its natio was 85.4 percent of all trees.
    The times when leaves were all of the tree were different by species, extenting from September to January of next year.
    The average value of the defoliation periods was 55±5days, corresponding to 24.4 per cent. And theperiods extended from 25 to over 90 days.
    The progresses of defoliation were divided in 7different types; three linear (A. B. C, ), Convex, Concave and sigmoid type to ordinate.
    The most fraction among them was the convex type (72 species, 36 per cent.)

    SUR LA FORMATION DE L'ÉSPACE EXTÉRIEUR, IL EXISTE BEACOUP DE THÉORIES. PARMI CES THÉORIE, AU POINT DE GRAND VUE, “PAYSAGE” EST LE PROBLÉME IMPORTANTE. DE CONSIDÉRER “PAYSAGE”, D'ABORD, IL FAUT QUE NOUS CONNAÎSSONS LA RELATION ÊNTRE L'HOMME ET LA NATURE. “PAYSAGE”, IL SE CLASSE TROIS, QUANT À CETTE RELATION.
    (A) “PAYSAGE” DE L'ÉPOQUE QUE L'HOMME VÉCUT PAR GROUPES DE CES FAMILLES.
    (B) “PAYSAGE” DE L'ÉPOQUE QUE L'HOMME VÉCUT COMME L'UNITÉ DE DIVERSES SOCIÉTÉS COMMUNES.
    (C) “PAYSAGE” DE L'ÊPOQUE QUE L'HOMME, IL SE MET À DISSOUDRE L'UNITÉ DE SOCIÉTÉS COMMUNES.
    (C) IL EST LA SITUATION CONTEMPORAINE. AUJOURD'HUI, IL FAUT QUE NOUS PENSEONS À LA CONSCIENCE DE SOI-MÊME SUR DIVERSES L'ÉSPACES EXTERIEUR AU POINT DE DIALOGUE MILIEU, CAR LE MILIEU EST “LE PAYSAGE CONTEMPORAINE”.

    The investigations on the relation between the early growth and the sown density about weeping love grase were carried out on the field for about 135 days from 28th June, '66, in order to get fundamental materials for cultivation and maintenance of vegetation on roadside slopes.
    Seeds were sown with 4 grades of density, i. e. 0.1gr/m2. 0.5gr/m2, 2.0gr/m2, and 8.0gr/m2.
    The results were obtained as follows;
    1) Germinating rate decreased, as sown density increased. The germinating rate in 8.0gr/m2 plot was 1/4 in 0.1gr/m2 plot.(Table 4 and Fig. 2)
    2) On the 135th day after seeding, the slope of the C-D curve became nearly 45° (C-D index a-1 in formula (1)), and the Y-D curve became a horizontal line (formula (3)). At that time final yield per each plot was constant independently of density (formula (2)).
    3) In the lower density plot (0.1gr/m2 or 0.5gr/m2), the values of dry weight per plant, number of tillers, the greatest width of leaves and also diameter of stock were greater. On the contrary, in the higher density plot (2.0gr/m2 or 8.0gr/m2), the individuals were feeble.
    4) In the earlier time of growth, the significance of top and root elongations among 4 plots were recognized, but as plants grew, the significances could not be found.(Table 6 and 7)
