These changes are usually first felt in the West and they drift east- ward. It is his business to judge the areas where similar changes will occur as far ahead as possible. Frosts and freezing temperatures usually accompany areas where the barometer readings are above normal, and Figure 1 is presented to show a composite chart typical of frost condi- tions in the North Pacific States. There are many modifications of this type having a particular bearing on individual localities, but their explana- tion cannot be given in a short article of this nature, for to do so would require an explanation of the dynamic forces underlying their behavior, and our story would become too long and technical to be readable, except to those who have made a special study of meteorology. The weather bureau has for many years issued frost warn- ings in every state, but it is only in recent years that the work has been specialized to meet local wants. Form- erly frost warnings merely mentioned the fact that the conditions were favor- able for a light or heavy frost, as the case might be, and that is still the rule in those places where no heating is done. Forecasts of this character, however, will not answer for the up-to- date orchardist who has gone to the expense of heaters and fuel and is pre- pared to lay out several hundred dol- lars a night for supplies and labor to insure his crop against frost. He wants to know just how cold it will get and when he should start his fires, so as to judge as to the probable length of time he will have to keep them burning. This information the weather bureau is prepared to furnish in part, and the part it does not furnish can be obtained by the individual without much expense of labor and time.
