be under the immediate control of the botanist in charge. Such 

 Si condition of things, as in the present case, is very likely to 

 result in injury to or loss of specimens. Some of the stored 

 specimens were destroyed by insects, some by moisture, having 

 been placed apparently where they became wet by a leak in the 

 Toof. A glass case containing puff balls was broken and its 

 contents spoiled or destroyed, and two boxes, one containing 

 specimens and the other mushroom models, could not be found. 



The room in geological hall which has been assigned to the 

 botanical department is on the second floor in the southern 

 ■extension of the building. It is divided into two parts, the front 

 part being used as a show room and containing the sections of 

 the trunks of our trees arranged in wall cases, and photographs 

 and thin sections of the wood of the trees exhibited in swing- 

 ing frames supported by upright standards. It is expected also 

 to contain table cases in which will be exhibited specimens of 

 •our edible and poisonous mushrooms and other plants or parts 

 -or products of plants that may have such importance or eco- 

 nomic value as to be of special public interest. The rear part 

 ■of the room contains the office of the botanist, the library, the 

 herbarium and duplicate specimens together with specimens of 

 •t^xtralimital species. It will also be used in part as a botanical 

 workroom. 



Several species of thorn recently described, having been 

 reported as occurring at Crown Point, that locality was visited 

 late in May with the purpose of collecting fl^owering specimens 

 for the herbarium. The thorn shrubs and small trees were 

 found in abundance along the northern and western shores of 

 the promontory, and about the ruins of the old fort. Their 

 leaves were generally badly infested by plant lice, a condition 

 which it is said is repeated every year. The cockspur thorn is 

 the prevailing species and was in better condition than the 

 •others. The large fruited thorn, Crataegus punctata, 

 the long spined thorn, C. macracantha, the Champlain 

 thorn, C. c h a m p 1 a i n e n s i s, Pringle's thorn, C. p r 1 n - 

 g 1 e i, and the pruinOse fruited thorn, C. p r u i n o s a, were 

 found there. 



The last three are additions to the previously known species 

 •of our flora. The red seeded dandelion, Taraxacum ery-
