Users of wet iind dry bull) 

 hygrometers will find the fol- 

 lowing table, compiled at th(* 

 Forest Products Laboratory. 

 Madison. Wisconsin, very use- 

 ful for ciuickly determining 

 relative humidity values from 

 wet and dry bulb thermometer 

 readings. To use the table, 

 read the temperatures and 

 ■ ubtract the wet bulb readings 

 from the dry. Locate the ver- 

 tical column of figures headed 

 by the appropriate difference 

 between wet and dry bulb 

 readings, and the horizontal 

 row of figures beginning at 

 the extreme left with the ob- 

 served dry bulb reading. The 

 figure marking the intersec- 

 tion of these rows is the rel- 

 ative humidity value expressed 

 in per cent. 



Take the following as an ex- 

 ample: wet bulb temperature 

 132 dtt.»ree3 Fahrenheit; dry 

 bulb temperature 1 40 de- 

 grees; difference 8 degrees. 

 The figure marking the inter- 

 section of the vertical column 



for 8 degrees difference with the horizontal row beginning with 1 40 

 at the extreme left, is 79, which is the correct relative humidity for 

 the given thermometer readings.

Is Prosperity Ahead? 



The following interesting comments on current business condi- 

 tions were recently sent to the members of the Central Bureau of 

 Furniture Manufacturers by M. Wulpi, commissioner: 



The situation business has passed through the past ten months 

 is not to be wondered at, when it is realized that the Big War upset 

 conditions of every kind, and carried its detrimental effect into 

 every phase of human life and activity. The one Big Wonder is, 

 that we seemingly are getting out from under it so rapidly. It took 

 the country eight years to recover from the C'ivil War, which was 

 not nearly as far reaching as the late one. 



"The big commercial question at this time is 'What is this Fall 

 gomg to see? Naturally, the buying activity and power of the 

 farmer is as big a unit towards the answer as any other. The 1 92 1 

 crop is big. There are almost six and a half million American 

 Farms. Will they buy this Fall, and to what extent? 



A farm journal publishing house recently issued an inquiry to 

 12.824 farmer 'Smiths' on its 1.100.000 subscription list, as a fair 

 representation for general results. The question was: 



" "What would they do with this harvests' cash?' 

 The returns were heavy. Computing the percentage in returns 

 the following deductions were made: 



"Of the total 1,100.000 farmers, 5 13,700 will paint this or next 

 year. 



"42,900 will build houses this year. 



"38,500 will build next year. 



"40.700 are planning to build barns. 

 "1 5,500 are planning to build houses and barns. 



"786,500 buildings to be built. 

 1 9 I ,670 buildings repaired or remodeled. 



"862,000 farm buildings built, repaired or remodeled. 



"521,400 build or repair fences this fall. 

 95,800 build or repair fences next year. 



"115 10 of the Smiths will buy autos this fall, making 126,500 

 autos to be purchased by the 1,100,000 farmers, 13 7.000 already 

 decided upon as to makes for this year and next. 



"They are to purchase 17.600 motor trucks this fall, and 2,100 

 next year. 



"8,300 motorcycles this year. 



"68,500 will purchase lighting plants. 



"33,100 will install heat plants. 



"28.800 gas engines to be purchased. 



"78.100 washing machines. 

 120,300 musical instruments. 



"33,100 tractors. 



"100,000 implements. 



"5911,503,000 estimated total purchases, by the I. 100.000 on 

 this journal's list. 



When it's considered that this is but one-sixth of the total farms 

 and refers to only the main items, the total cash to be expended will 

 run into vast sums from this medium alone. 



How many other wheels will this put into motion? One indus- 

 try interlocks into another and if all move, what a tremendous 

 machine it is. Let but a few cogs stop and the effect is far-reaching 

 and to the reverse, let one start off well, how many others it will 

 drive. 



So while the whole business machine may not get to humming 

 this fall, it is confidently expected that it will get into such motion. 

 that by next Spring you will hear prosperity's tune. Let us 

 hope so. "
