The minimum tem- peratures are for such nights as re- mained clear and with very slight air movement, which was from the south. An aneroid barometer is also a valuable instrument. By carefully noting the movement of this instrument one may readily learn to predict with more or less certainty the kind of weather to be expected. With the pressure high the chances are that frost may be expected and the reverse when the pressure is low. In making readings with all me- teorological instruments there should be a set time for observations. Random readings, taken at odd times? are of very little value. A careful record will surely repay the observer many times for his trouble. It would be a very fine practice for each grower to be able to tell what were his maximum and minimum tem- peratures, barometer, wind direction and estimate of velocity, dew-point tempera- tures and rainfall for each day in the year. This data would not only be valu- able to himself, but to the district as a whole. Lastly, whenever it is possible get the weather from the nearest United States Weather Bureau station.
