Insects in.juuious to the blackberky, J. B. Smith (lij;s. 7). — 

 ropiihir dcseriptious arc given of the red necked Ciine Lorer {Af/rilu>i 

 rnJicoUis), blackberry crown borer {Bemhecia niarf/inata), giant root 

 borer {L'n'oriKs laticoJIis), and blackberry niidgc {LitsUtpieru fnvinosa)^ 

 uitli suggestions regarding remedies. Special leferences are )n;ide to 

 observations on these insects by the author in 1891 in soulliern New 

 Jersey. Three of the figures accompanying the text are original, the 

 others being after liiley. 



Tlic hintory of the gall maker has been inorr coiniilcti'ly written jnnl tlie dates of 

 lli(! various stages have been fully uoled, wliiie oliservatioiis on the crown borer are 

 for the lirst time carried on throughout an entire season, somewhat modifying the 

 accepted accounts, for New Jersey at least. " * '" 



The life history of the crown borer differs from tlinse jireviously published, in giv- 

 ing a 2-year period to the larva, the others giving positivtdy or infcrentially a 

 period of 1 year only. * * * As a blackberry pest tiie J'rioints larva has not, to 

 my knowledge, been heretofore recorded . * * ^ 



In some States rasjiberries suffer equally or more from these same insects, l)ut in 

 New Jersey the varieties grown are practically free from injury, so far as I have 

 observed. Of the blackberries the Wilson, which for date, size, flavor, and price is 

 tlie favorite with growers, is also the favorite with insects, and is the only one 

 injured to any serious extent. I ail inclined to believe that other varieties are also 

 attacked, but ai'e more resistant and show injury less.

Oyster shells as food for laying hens (pp. 3-10). — It is 

 explained that the value of oyster shells as a source of material for 

 egg shells has been questioned, it being claimed that its value for poul- 

 try lies solely in furnishing grit. To test this an experiment Mas made 

 with six 1-year-old Leghorn hens, three of which were fed coarse ground 

 oyster shells iind three coarse broken glass instead. Both lots were kept 

 confined in cleanly swept pens having a floor of matched boards. In 

 tlie first period, INIarch 30 to April 10, wheat, fresh cabbage, and a 

 grain mixture composed of corn meal, wheat bran, wheat middlings, and 

 old-process linseed meal, were fed to both lots ; and in the second period, 

 lasting until ]May 3, boiled eggs were added. The eggs were collected 

 the last 10 or V2 days of each period. The ]>ercentages of water, ash, 

 and calcium carbonate contained in each kind of food and in the eggs 

 laid each period, and the amount of food consumed are tabulated for 

 each lot. The results for tlie lot receiving oyster shells were as follows: 



During the first period the hens laid 12 eggs, 1 pound of eggs being produced from 

 3.9.5 pounds of water-free food. These eggs contained calcium eqnal to JS.-13 grams 

 of carbonate of lime, the .shells alone containing 47.74 grams. The grain and cab- 

 bage consumed and the drinking water given ilieni contained altogether calcium ef|ual 

 to 7.62 grams carbonate of lime. The oy.ster shells taken by them contained 93.80 

 grams carboinite of lime. 



During the second period the hens laid 21 eggs, which were produced at the rate 

 of 1 i)onnd for every 2.59 pounds of water-free food. These eggs contained calcium
