EXPERIMENT STATION REPORTS. 115 



THE ORCHARDS AND GARDENS, 



The balance of the south block of api)le trees was thinned out this 

 yeai-, leaving the trees two rods a|)art. About fifty trees, varieties that 

 had proved to be valueless here, have been top worked to standard sorts, 

 like Baldwin, Spitzenburj>\ etc., of which ^^•e now have very few on the 

 college grounds. Part of the middle block of apples Avill be thinned like- 

 wise the coming Avinter. ^Many worthless varieties have been cut out 

 of the variety pear orchard and the orchard has been seeded to clover 

 for three years to check blight. A small commercial plum and quince 

 orchard has been ])lanted and tlie sour cherry orchard extended. Com- 

 mercial plantings of raspberries and blackberries have been made, for 

 breeding experiments. AVe propose to plant a commercial vineyard of 

 one and one-half acres next spring and a commercial pear orchard of 

 three acres. These commercial plantings are of but one to three standard 

 varieties, so that they may be used for experimental purposes. No ex- 

 l)eriments with vegetables are now under way, except the potato breed- 

 ing work already noted.

REPORT OF THE ENTOMOLOGIST. 



Prof. C. D. Smith: 



Following is a brief report of the work of the division of entomology 

 during the year ending June 'iO, 1007. 



On bulletin has been issued during the year, viz. : No. 244 being ac- 

 counts of a number of insects which were new or little known in Mich- 

 igjin, also of some that were of especial interest just at that time. 



Two very serious ]iests are at present doing injury in our state, one 

 the Imjtorted La]'ch Saw-tly (Jji/gacoucmatiis o-iclisoiiii ) which is kill- 

 ing off large tracts of tamarack in the northern half of the state, and 

 the other, llie Mediterranean Flour-moth (Ephctttin Inihniclla) . This lat- 

 1er ]>esl is a small delicat<» creature which ]>robably came from Euro]>e. 

 It has appeai-ed in many of the several slates in tlie United Stales and 

 has now l>ecome firmly establisluMl in ^ri<-higan. It works in flouring 

 mills, sj)inning webs tlii-oughout (roughs, elevators and elsewhere, clog- 

 ging the machinery and binding tlu' flour into felted masses. Fumiga- 

 tion has been the standard remedy in other jilaces and no doubt we 

 shall be obliged to resort to it here. 



A number of trips have been made to investigate various invasions 

 of insects, one to Petoskey and vicinity to look up the lai-ch saw-fly, one 

 to Paw Paw to look after a beetle iAnomala lji)iotata) that was feed- 

 ing on young apple trees. A trip was also made to Benton Harbor to 

 address the Berrien Countv Horticultural Society and one to Bancroft 

 to address a farmers institute. 



Several trips have been made to look into reported invasions of the
