This article considered "the powder magazine" of the Nagoya Castle the third division which the J. Conder investigated after the Nobi earthquake, and it's following points to become clear.
The notch was worked to the basis of the Nogi warehouse. Conder reported that the construction of the Nogi warehouse was carried out by the direct management of the military, the cost of construction with 5,363 yen, and tsubo unit price 145 yen. The drawing of the Kiko library is different from the basis cross section of the powder magazine to show in a part, but both resemble closely. The third division "powder magazine" which Conder reported is regarded as Nogi warehouse located at the Fuke-maru by the comparison of structure and dimensions. Because dimensions of the ground plan and the elevation are equal at the rate of 99%, I judge that the spare powder magazine of the Kigo library is the Nogi warehouse. Condor might acquire the drawing document through the Aichi prefecture.
