written a statement to exp.ain thoroughly the difference be- tween the three most common forms of storms and to set at resd any differences of opinion there may be among the 'laity" as to their various origins and forms. He says:
 Disturbances i'll the atmosL Dhere commonly called storms. may be divided into. three clas- ses ,namely y, cyclones. hurricans and tornadoes. Each has char acterlstics of it's own by which it may be distinguished from the others.
 Cyclones occur in one part or another Of our country everyday of the year. This explains the req son why cyclones should not be called tornadoes. Cyclones come from the northwest or southwest and after crossing the country (usually in three or four days) they pass out to sea, over the north Atlantic states. They, vary in diameter from a few hundred to thousand miles, and are not always attended by high winds. It is through the agency of cyclones that nature distri- butes the rain that is necessary for the growth Of crops and makes rivers navigable.. ln the n nSfn n OF hnf is moving northward the wealth CT IS usually warm and rainy, with easterly winds while in the western half the weather is'cool with decreasing rainfall, and westerly winds, The winds with in the cyclone blow inward to- ward the center in gently curved lines and in the direction opposite to the motion of the hands of a clock. Cyclones occur more fre- quentiy and are more vigorous 5n winter than in summer. After q long heated spell i'll summer. it is the advent of the cyclone that brings the refreshing show CTS.
 Hurricanes in this part of the world usually come from the sOuth or southeast but never from the northwest land most of them originate in the Carib- bean sea. They travel northwest ward until they reach Florida or the gulf coast and thence north eastward toward the North At l. lantic states. They occur most Frequently from June to October and are very destructive. Near the center the winds attain ye,- ocities of 60 to 80 miles per hour an dthe general circulation ar ound the center is about the same as that Of the cyclone. Their average diameter is a. bout TOO miles. The storm that devastated Galveston on Septem Der 1900 was a typical hurricane.
 ''TornadOes are much smaller in size and more destructive than hurricanes, They occur in the eastern quadrants of the, larger cyclones and are caused. primar- fly by the unequal. heating of different masses of air which causes an unstable equilibrium Of the atmosphere. Few states east of the Mississippi river are free from their yisitations but they | are more frequent in the MisSiS- sissippi and Ohio, valleys than else where. In fair weather smapl tornadoes are called whiriwinds and at sea they are known as watersypouts. In the tornado the motion of the ail' is spirally in ward toward the center and(u , ward. At the surface of the earth tornadoes are rarely, more than a few hundred yards in diameter and sometimes only few rods. They usually move in northeast erly direction with great rapid ity and after travelling, a few miles are dissipated. They are preceded by unusual heat and are invariably accompanied by Tightening and rain and some times by hail. Some. tornadoes have a pendent, funnel-shaped cloud with rotary winds which may reach velocities of 200 miles per hour.
