d\T.amite, 100 feet of 6-inch drain tile and 12 concrete tile caps. 



The procedure recoramended tc determine whether subsoil drainage is 

 feasible is as follows: Hake a soil profile at the wet spot showing (1) deoth 

 of top soil, (2) depth of impervious subsoil, and (3) depth of sand, gravel or 

 water-carrying strata, if any. If the water-carrying stratum is close enough 

 to the surface to indicate that blasting v/ill remedy the wet condition, there 

 still remain., the question of whether the water-carrying stratum can take care 

 of the additional surface v.-ater drained into it during periods of heavy rain- 

 fall. Since there is no economical way to determine this in advance, the only 

 answer is to try it out. It has been found that if sand or gravel lies within 

 10 feet of the surface, the Irnd ovmer has better than a bO-50 chance of getting 

 satisfactory vertical drainage by blasting with dynamite.

That peach and apricot trees in the South often fail to leaf out or 

 bloom until almost midsumjTitr because of too little cold vreather during the

That leafhoppers have been found to decrease photosynthesis of apple 

 leaves almost 25%J Under these conditions size and quality of fruit are likely 

 to suffer. 



That an electric fence 62 miles in length has been erected in Florida 

 to protect crops against deer? This barrier is a 6-strand barbed wire fence 

 about 7 feet high and extends from La'ce Okeechobee to Fort Myers. 



That the so-called Gloucester scries of soils covers a greater area in 

 Massachusetts than any other? The total percentage of our land area covered

That the tolerance on arsenic and on lead, established by the Fool and 

 Drug Administration, has been changed five times since 1928? The tolerance on 

 arsenic that year was .03 grains per pound, in 1929, .02;j; 1930, .02; 1931, 

 .012; 1932-1939, .01, and 1940, .02C. The tolerance on lead is now just twice 

 that amount, .05 grains per pound. 



That a pollen grain under favorable conditions will germinate within 

 30 minutes a-^ter it reaches the stigma of the blossom? If the temperature is 

 favorable, many pollen tubes mav traverse the style of the apple and plum
