evidence on that tree. A nearby Mcintosh tree showed considerable maggot 

 injury in the fruit and sonie of the apples had already dropped because of 

 maggot infestation. Several flies were observed in this tree. Practically 

 no maggot damage vias apparent on the Baldv/ins. These observations support 

 the testimony of entomologists who find that maggot flies attack early var- 

 ieties such as Transparent, Astrachan, Gravenstein, etc. to a greater extent 

 during July and August. The Porter variety has long been considered a favor- 

 ite of the apple maggot. These apples soften up readily and provide an ideal 

 place for the maggots to develop vrhen the apples drop. This brings up the 

 question, V.Tiere do maggot flies go after the apples have dropped from the tree? 

 If they are still interested in laying eggs it is logical to assume that they 

 will seek other trees the fruit of which is not j'^et infested. Perhaps they 

 move from trees of summer or fall varieties to trees of winter varieties. 

 This may account for the appearance of the flies in Ealdviin trees as late as 

 September. It is quite obvious that if the above mentioned Transparents vrere 

 gathered up promptly and destroyed there would be fevcer flies to infest later 

 varieties. Furthermore, this Transparent tree which will not bear a crop in 

 1942 will make its influence felt in the rest of the orchard as thousands of 

 flies emerge from the ground beneath it and sally forth in search of a home.

That the production of plows for tractor use exceeds the production of 

 horse dravm plows in the United States? Disappearance of horses and mules on 

 American farms in 20 years has taken away the capacity to consume the food 

 from 70 million acres, according to the census. This is more than the entire 

 farm acreage of lovia and Missouri combined, and v/ould be sufficient to feed 

 84 million human population. 



That the first half bushel of Michigan's Redhaven peaches brought a record 

 price of $30? This was the first commercial offering of the new variety on 

 the Benton Harbor market. It is said to have excellent shipping qualities and 

 if of a brilliant red color. 



That the annual output of United States fruit canning plants amounts to 

 about 50 million cases? Peaches lead v.'ith over 12 million cases. 



That the canned fruit and vegetable requirements from the 1941 pack for 

 the armed forces of the United States will amount to about 7,900,000 cases of 

 canned vegetables and 2,250,000 cases of canned fruits? This estimate includes 

 the combined requirements of the Civilian Conservation Corps, Coast Guard and 

 Marine Crops, as well as the Army and Nav^'-. 



That sulphuric acid mixed with citrus pulp makes a plastic from which 

 Florida citrus field crates possibly may be made in the future? This new dis- 

 covery is part of a recently started i" 50, 000 program of citrus research. 



That Boj'senberries, Youngberries and Nectarberries account for more than 

 56 per cent of all bush berry shipments to the Los Angeles and San Francisco 

 markets? Raspberries rank second in popularity with common blackberries third 

 and Loganberries fourth. 



That a nev; method of determining winter hardiness in apple root stocks 

 has recently been developed by U.S.D.A. workers? The test consists in freezing 

 at 20° F. large numbers of apple seedlings and then selecting from the frozen 

 plants the small number that show little or no injury, '
