But it would be indispensable to have a maximum and minimum thermometer for determining the nocturnal temperature and those of the springs at Kusatsu which vary several times during the day.

Before entering upon any detail it may be well to state that the traveller can go in a carriage and in one day from Yedo to Takasaki (about 25 ri.) There is even a native service between the two points. The road is often in bad order, and the carriages are inferior. In journeying by short stages the following is the itinerary which I should recommend, and which I myself followed. Grand halt at Ômiya. Sleep at Okegawa. Morning, cloudy. Day fine with a gentle breeze S. W. Water drinkable 16°. Grand halt at Kumagai. Sleep at Honjô. Morning cloudy. Day fine. Gentle breeze S.W. Water 16°; at Kumagai 15°, 5° and 14°.
