PARK AND CEMETERY. 
by the wealthier Mexicans and more particularly 
those of the conservative element; that is, those who 
are still adherents of the Church at Rome. It might 
still be called the French cemetery however because 
of the French taste displayed in it. The profuse 
employment of cast iron ornaments, the bronze let* 
ters upon the marble slabs, and the nomenclature 
throughout, are all French. There is a religious 
tone felt in this cemetery as in no other in Mexico. 
A religious sentiment appears upon the gateway. 
There is a row of graves of sisters of Charity, (now 
no more seen, living in the City of Mexico,) and 
here and there, one may find the grave of a priest. 
The tombs are generally of more artistic design 
than in any of the other burial places and it is re- 
freshing to see that religious symbols are not wholly 
tabooed here. 
It may be that Mexico, so progressive of late, 
will, as the years go by, compare the other ceme- 
teries with that of La Piedaa, and strive to bring 
the others up to the standard of this But at pres- 
ent the Mexican cemetery generally offers but one 
suggestion to those who are interested in the sub- 
ject of “How to beautify burial places so that they 
will furnish wholesome lessons to the living” — and 
that is, how not to do things in preparing a resting 
place for the dead. L. Viajero.

THE ECHINOCACTUS, OPUNTIA AND MESEMBRYAN- 
THEMUM ALLIANCE. 
( Continued .) 
Echinocactus has 200 or perhaps 250 species, 
with a number of varieties. They are mostly Mexi- 
can, but some thirty-two species and varieties ex- 
tend to the United States. E. Simpsoni and E. 
Whippleyi in variety are found in Colorado. The 
majority, however, are found along the Mexican 
boundary in California and Texas, etc. Some spe- 
cies attain to a large size, and many are curious 
and attractive. 
Eriosyce is a monotypic plant from Chili. 
Disso-cactus has two or three species in the West 
Indies and Brazil, one of which has been in cultiva- 
tion as a phyllocactus. 
Cereus is credited with 220 species in tropical 
and sub-tropical North and South America, the 
West Indies and the Gallipagos Islands. About 
forty forms are credited to the United States, either 
natives or naturalized, with twice or thrice as many 
names, and more being invented. They are very 
variable in habit, globose, erect, or climb- 
ing, and their flowers are often the most 
gorgeous imaginable. C. caespitosus, C. gona- 
canthus, C. paucispinus and C. aggregatus 
have been found in Colorado. Many are found 
along the Mexican border, C. tiiangularis (not 
Napoleonis) and C. nionoclonos are naturalized on 
some of the Florida “keys” — (islands). Several 
species have become wild in the drier regions of 
the old world within or bordering upon the tropics. 
The night blooming species never lose their inter- 
est, for there are always great 
numbers of people to see them 
for the first time. Many of the 
smaller species (like some or- 
chids) bloom more freely when 
but recently imported. 
Eulychnia is a monotypic 
genus from Peru and Chili. 
Phyllocactus has thirteen 
species and several varieties, 
natives of Mexico, Central and 
South America. Of late years 
a few European hybridists have 
turned their attention to these 
plants and to Cereus, and sev- 
eral handsome night and day 
blooming varieties have been 
raised. Such plants as P. lati- 
frons are easy rivals of the 
night blooming cereus, quite as 
handsome in flower and more
