1) In the case of single measurement which has been made for 3 times replication with 2 levels of the factor of instrument, 4 levels of the factor of subject height, and 3 levels of the factor of individual, it has been cleared that the difference of instruments Aso and Weise has become heighly significant.
2) At this actual measurement, the quantity of error in sample mean for Aso is smaller than that for Weise. Accordingly it is needless to say that Aso is more accurate than Weise. Moreover As-6 is supposed to be exact, beause of having been smaller in the error variance of sample.
3) In the case of 1) the difference among individuals, with α=0.05, has become non significant.
4) In consequence of 2 times replication with 4 levels of the factor of subject height and 4 levels of the factor of distance of measuring point, in the case of using Aso and Weis each, the following has been acknowledged. On Aso, both factorial effect of subject height and interaction, with α=0.05, have become significant. On Weise, factorial effects of subject height and the distance of measuring point, and interaction have become non significant with α=0.05.
5) In consequence of 3 times replication with 3 levels of the factor of individual, 4 levels of the factor of subject height, on Christen, factorial effects of individual and subject height, with α=0.01, and interaction, with α=0.05, have become significant.

In this report, the following correlations are investigated by the method of small samples; ray-volume (V_R) and shrinkage (α_t, α_r) in the transverse section of wood, ray-volume (V_R) and anisotropic grade (α_t/α_r) of shrinkage in the section, and area (S) of attached surface of ray knd tracheid each other and radial shrinkage (α_r) of wood. The results are obtained about the normal sap-wood of single Sugi (Cryptomeria japonica DON.) -bole (statistically the population) are as follows (cf. Table 5);
(a) Correlation of V_R for α_t/α_r is as small as negligible, but it is not said that correlation is no existence at all (0.13≤ρ≤0.75 D. C. 95%).
(b) The checking activity of ray for α_r is negligible.
(c) The correlation-coefficient of V_R for α_t is positive (0.06≤ρ≤0.73 D.C. 95%). It seems to be the result of numbers of cell walls in tangential direction increased by the presence of wood rays.

From the ether-extracted residue of alcohol extract of fruit-body of Fornes pinicola, two substances, A [mp. 260-263°C (decomp.), [α]¹⁵_D+ 8.6° (in pyridine)] and B [mp. 305-308°C (decomp.), [α]²³_D=+43° (in pyridine)] having their formula as C₃₀H₄₆O₄ were isolated. They have one double bond and one carboxyl group, and were likely to belong to triterpenoid on color-reactions. In A one carbonyl group is ascertained as 2, 4-dinitrophenylhydrazone, but from B carbonyl derivative is not obtained. A gives a methyl ester mp. 181-181.5°C, [α]⁹_D=+20.8° (in chloroform) and a monoacetate mp. 177-180°C, and B gives a methyleester mp. 178-178.5°C [α]⁹_D=+44° (in chloroform) and, as an acetate, a needle crystal mp. 160-162°C, though its formula is corresponding to C₃₂H₄₆O₈.

(1) The vibration method of indirect tensionmeasurement for any existing skyline logging cable is proved by the authors' experiments to be very convenient and considerablly accurate.
(2) The values of cable tension measured by the propagating velocity of the vibration waves may be utilized for practical purposes in many cases.
(3) Probable maximum tension, Tmax, of a skyline cable, on which a single concentrated load is applied, is given by the formula,
Tmax=γ·T
where, T denotes the value of tension of the same cable measured by vibration method when no load is applied on it. Coefficient γ is theoretically caIcurated by eqs. (3), (4), (5), according to form and weight of cable and amount of löad applied on it.
(4) Tabulated numerical values of coefficient γ may be very useful for practical procedures.
