 The  Crab-Apple  of North-America.  This  showy  species  is mentioned  
 here  as worthy  of  trial-culture,  since  it  is  likely  th a t  it would  
 serve well  as stock  for  grafting.  Best  grown  in  glades.  Wood nearly  
 as  tough for  screw-work  as  tliat of  the  pear-tree  [Robb], 
 Pyrus  communis,  Linné.* 
 The  Pear-tree.  Middle  and  Southern  Europe.  Western  Asia.  
 Well  known  even  at  the  time  of  Homer.  Introduced  into  Britain  
 already  by  the Romans,  and  many varieties were  cultivated  in  Ita ly   
 a t  the  commencement  of  the  Christian  era  ;  pears  were  available  
 also  to  the  lacustrine  people  of  Switzerland,  Lombardy  and  
 Savoy,  but  seemingly  not  so  extensively  as  the  apple.  Prof.  C.  
 Koob  regards  the  Chinese  Pyrus  Achras  (Gaertner), which  is  the  
 oldest  name  for  P.  Chinensis  of  Desfontaines  and  Lindley,  as  the  
 wild  plant  from  which  all  our  cultivated  varieties  of  pears  have  
 originated.  The  pear-tree  is  cultivated  up  to  10,000  feet  in  the  
 Himalayas  ;  like  the  appie-tree,  it  sets  uo  fruit  in  tropical  lowlands,  
 hut  on the  other  hand it will bear  a  good  deal  of  frost,  being  grown  
 iu Norway  to  lat  63“  52',  and  still  bearing  fruit  there.  I t   needs  a  
 deeply  pervious  soil,  more  so  than  the  Apple-tree.  In   Victoria  
 defoliation  takes  place  in May,  perfection  of  new foliage  in October.  
 The  tree  attains  an  age  of  over  300  years,  fully  bearing.  A t  
 Yarmouth  a tree  over  a  100  years  old  has  borne  as many  as 26,800  
 pears  in  a  year  ;  the  circumference  of  its  crown  is  126  feet.  A  
 Huffcap  Pear-tree  a t  Hadley,  in Worcestershire,  yielded  two  hogsheads  
 of perry  in  each year for  a  lengthened period  [Masters].  Pear-  
 wood  is  used  by  wood-engravers,  turners,  and  instrument-makers.  
 A  bitter glycosid,  namely  phlorrhizin,  is  obtainable  from  the hark  of  
 apple-  and  pear-trees,  particularly  from  that  of  the  root  ;  while  a  
 vo  atile  alkaloid,  namely  trimethylamin,  can  be  prepared  from  the  
 flowers.  Pyrus  auricularis, Knoop  (P.  Polveria,  L.),  the  Bollwiller-  
 Pear,  is  a  hybrid  between  P .  communis  and  P.  Aria,  Ehrhart.  
 Curious  fruits  have  been  produced latterly  in North-America  by  the  
 hybridization  of  the  apple  with  the  pear.  .Hybridization  of  the  
 Pear-tree with  the  Quince-tree  has  hitherto  not  produced  superior  
 fruit  in  either  direction.  The  Chinese  and  Japanese  Sand-Pear  
 furnishes  excellent  stock  for  grafting  [E .  Goeze],  The  Muscatel-  
 Pear  is  particularly-sought  by  confectioners  [Mathieu].  Pears  for  
 preserving  should  be  halved,  boiled  20  minutes  with  6  ounces  of  
 sugar  to  a  quart  of  water  [Shelton].  From  the  variety  “ Le  Conte”  
 pears  to  the weight  of  27  ounces  have  been  raised  in  Texas.  The  
 generic writing  of  Pirns  is  inadmissible,  as  even  Plinius used  both  
 Pirus  and Pyrus in his writings, and  as the  latter wording was already  
 adopted by Malpighi  and fixed for the genus by Linné.  The flowers of  
 all the leading European fruit-trees afford nectar for honey to bees.  To  
 subdue  the Fusicladium-rust or  scale  ou  pears  and  apples,  the  trees,  
 just after  flowering, should  be  syringed with  a  solution  in the proportion  
 of  1  lb.  sulphate of copper,  1  lb.  of  slaked lime,  and  4  gallons  of 
 water, which  operation  is  to  he repeated  a month  later  [R.  Goethe].  
 A   modified  “ Ean  celeste”  for  the  same  purpose  is  prepared  by  
 dissolving  in  1  quart Ammonia-liquid from 4 to  6  ounces  carbonate of  
 copper,  and  diluting  this with  25  gallons  of  water.  Attacked  here  
 also  by  the  Codlin-moth.

 The  Quince.  Countries  at  the  Caspian  Sea.  Reared  in  South-  
 Europe  from antiquity;  in  the Himalayas  its  culture  readies  to  5,500  
 feet  elevation,  iu  Norway  to  Christiania.  The  Portuguese variety  
 bears  extremely large  fruit.  The  preserved quince is one  of  the most  
 agreeable  of  fruits.  Quinces  boiled  into  mash  and  thus  consumed  
 with  milk  are  a most  refreshing  and  wholesome  food.  The  seeds  
 impart  copiously  to  water  a  tasteless  mucilage.  Quinces  are  not  
 readily  attacked-by  sparrows.

 The  Medlar.  Southern  Europe,  Western  Asia.  The  ordinary  
 medlar-fruits  become  edible  after  some  storage.  A  large-fruited  
 variety  of  excellent  taste  is  cultivated  in  South-Europe.  P . Maulei  
 (Masters)  is  a  closely  cognate  plant, with  golden-yellow  edible  fruit,  
 particularly  fit  for  preserves.  Medlar-Jelly  has  come  recently  into  
 use  through Mr.  T.  F.  Rivers.  The  tree  has  fruited  at  Christiania. 
 Pyrus  Japónica,  Thunberg. 
 Jap an .  One of  the  prettiest of small  hedge-bushes, and  one  of  the  
 earliest  flowering.  Under  favorable  circumstances  it  will  produce  
 its  quince-like  fruit  of  good  quality.  I t   is  one  of  the  earliest  species,  
 so  valuable  to  the apiarist. 
 Pyrus Malus,  Linné.* 
 The Apple-tree.  Europe, Western Asia,  ascending  the Himalayas  
 to  11,000  feet.  Shown  to  have  been  in  culture  already  in  Switzerland  
 and  Northern  Italy  prior to  historic  records,  though  Professor 
 C.  Koch  regards  neither  the  wild  and  variable  crab-trees,  nor  the  
 pear,  as  original  denizens  of  Middle  and  Northern  Europe,  but 
 simply  as  strayed  from  cultivation  and  degenerated.  Bees  resort  to  
 tbe  flowers.  For  reference  to  varieties  Dr.  Hogg’s  fruit-manual  is  
 also  in this instance most handy.  Koch traces some sorts  of  cultivated  
 apples to P .  pumila (Miller) of  South-Western Asia ;  as other original  
 forms  he  notes  the  P .  dasyphylla  (Borkhausen),  P .  silvestris  and P.  
 prunifolia  (Willdenow)  of  Middle  and  Western Asia.  This  tree  is  
 one  of  longevity  ;  Mr.  II.  C. Hovey  gives  records  of an  apple-tree in  
 Connecticut, which  at  the  age  of  175  years measured  about  14 feet in
