Charles Darwin on *' Crossing with Foreign Stock." A part of it was printed 

 in the Aiuerican Journal of Science and Arts, and Dr. Gray writes: "The 

 experiments are very neat and to the purpose." I planted 75 varieties of 

 Indian corn, 20 of onions, 250 of potatoes; continue many orchard experi- 

 ments, try to change the bearing year of apple trees; enlarge the arboretum; 

 graft potatoes on tomatoes and artichokes on sunflowers for a purpose; cross 

 tomatoes, gooseberries ; hybridize raspberries ; root prune corn; try to see if 

 pollen affects all corn the first year ; try to hybridize red and alsike clover; 

 try to feed the leaves of tomatoes, petunias, and martynias with soup; test 

 many sorts of vegetable seeds sold by best dealers ; stiirt a botanic garden ; 

 write for the report a popular account of the trees on the College grounds. 



1879. In this volume is a report of tliree lectures at farmers' institutes on 

 " Experiments Made at the College." This includes something in reference 

 to the growth of the trees in the arboretum ; burying in bottles over 20 sorts 

 of seeds to be taken up years hence to test their vitality; burying sticks of 13 

 kinds of timber in two places to see if it is best to set posts " top end down ;" 

 test vitality of buggy peas; test value of bumble bees in fertilizing red clover; 

 observations on the time of blossoming of Indian corn; test the vitality of 

 pollen one year old; try various sorts of bands to catch codling moths. The 

 report is complimented by the Country Gentleman as "containing, as usual, a 

 large amount of interesting practical matter." The Botanical laboratory is 

 built, costing about $3,500. 



1880. This gives an account of some results of experiments in different 

 modes of cultivating apple trees. A lecture on Indian corn was given at three 

 farmers' institutes.
