tunate as to have screech owls attach them- 

 selves to his orchard should consider him- 

 self especially favored, for the good they 

 will do in keeping mice down 's beyond 

 calculation. Now that mice are becoming 

 such a menace to many orchards, certainly 

 ever)'thing possible should be done to pre- 

 serve these owls. They are with us the 

 year around. 



Another thing about the owl and one that 

 is particularly valuable, is that it hunts for 

 food at night when most other birds are at 

 rest. It thus follows up the day-work of 

 the rodent-eating hawks, providing a con- 

 tinuous check on the four-footed vermin 

 of the ground. 



Practically all birds have some value to 

 us. There are many more that have not 

 been mentioned in this article. Some that 

 must not be overlooked are members of 

 the finch family. There are largely seed 

 eaters, destroying immense quantities of 

 weed and grass seeds. Blackbirds also live 

 on insects and seeds. There are the little 

 chicadees, and nuthatches, who spend thel 

 winter in large flocks, always busy hunt- 

 ing on the bark of the trees the small 

 insects the woodpeckers overlooked. 



The fly catchers, including the phoebe 

 birds, and king-birds are capturing their 

 food supplies from the air throughout the- 

 summer. Last but not least in value are 

 the warblers, constituting a very large 

 family. The food of these birds is very 

 small insects, such as plant lice, including 

 aphis and scale, which are such a nuisance 

 to the fruit and vegetable grower. |

seventy per cent. This discovery refutes 

 the idea that nitrogen alone is responsible, 

 for the increase of the leaf growth. 



To quote from Mr. Long's article in 

 the Saturi/ay Evening Post: "This better 

 leaf production in the early growth stage 

 is especially important, because the leaf's 

 ability to absorb carbonic acid gas depends 

 upon its size. Therefrom follows the 

 fact — proved when Ricdel interrupted the 

 gas supply — that the young gassed plant 

 with its abnormally large leaves extracts an 

 extra dole of carbon also from out of the 

 ordinary air, so that carbon fertilization, 

 even if carried on for only a few days, in 

 the early growth period, largely increases! 

 the ul.timatc size and weight of the crop." 



The second great result from Riedel's 

 experiments was that even by gassing for 

 only a few weeks, crop yields of all kinds, 

 fruits, grains and roots, were immensely 

 increased in quantity, size and quality. The 

 increases ranged from 36 per cent to 200 

 per cent. Whereupon, Riedel declares that 

 carbon fertilization without other fertil- 

 izer promotes plant growth more effec- 

 tively than all ordinary fertilizers, when 

 these are used without artificially sup- 

 plied carbon dioxide. By ordinary fertil-
