§ 50. Botanical Object Lessons.— Wishing this spring to cultivate 
in a class of young boys a taste for the observation of nature, and 
having only ten minutes a day to spare, I had them bring such 
plants or parts of plants as they could, mostly specimens from the 
house areas or public squares, and gave them very little instruction 
till their discoveries called for it. I was surprised and delighted 
with the quickness of their observation when sharpened by a little 
encouragement. In general, nothing escaped them. One little 
fellow discovered the double serrature of a leaf, and another came 
rushing in at recess with a curiosity in the shape of a lilac leaf 
which had a slight tendency to be tri-lobed. I was very much in- 
terested in this instance, both because this slight irregularity had - 
arrested his attention while at play, and because in some of the 
Oleacex the leaves are compound. 
${51. Postage on Plants.—From the United States Mail and Post 
Office Assistant, New York, February, 1873, we extract the follow- 
ing: “The /aw fixes the rate for matter wholly or partly in writing, 
except book manuscript and corrected proofs passing between author 
and publisher, at three cents for each half ounce or fraction thereof, 
and the Postmaster-General has no discretion in the matter.” Ac- 
cording to this reading of the law, there must be no labels with the 
_ plants, and we have twice had to pay letter postage, because the 
words “ Botanical Cuttings,” or some equivalent phrase, had been 
written on the outside to explain the nature of the package. Upon 
our appealing to the Station-master, he stated that such was the 
present ruling in New York. 
$52. Arceuthobium in Sullivan Co.—I enclose a few specimens 
of Arceuthobium just collected in the town of Forestburgh, Sullivan 
County. This is still outside the limits embraced by your Cata- 
logue, but it is nearer than the other two known stations, and in- 
dicates a southern rather than a northern range. I looked for it in 
a recent trip in the Adirondack mountains, but in vain. Its occur- 
rence here is in greater abundance than in Rensselaer County, but 
in a similar locality, viz., on small spruces (Abies nigra) in a sphag- 
nous marsh.
